Welcome to my webpage! Research positions are available for prospective PhD, Masters, and Undergraduate students to work in the following state-of-the-art areas of 5G and next-generation wireless systems. If interested, please drop me an email with your resume. Please visit my research profile (Publications / Research) for more details. My research interests lie in the area of signal processing for communications including parameter estimation, optimization, sparse signal processing, and transceiver design for 5G and next-generation wireless technologies. In particular, I focus on i) channel estimation; ii) carrier frequency and timing offset estimation; iii) receiver design and performance optimization; iv) throughput analysis; and v) blind modulation classification for the following 5G/6G wireless technologies.
- Orthogonal time-frequency space (OTFS): It is a recently proposed two-dimensional waveform for high-mobility communication in 6G. OTFS places information symbols in the delay-Doppler domain to exploit the property that a highly time-varying channel appears almost stationary in the delay-Doppler domain.
- Filter bank multicarrier (FBMC): One of the waveforms which may replace OFDM in future wireless communications systems due to its robustness against practical impairments such as carrier frequency offset and timing offset.
- Millimetre-Wave (mmWave) Communication: It is one of the key technologies being used in 5G deployment. It allows mobile operators to address the massive increase in mobile data demand and to expand 5G into fixed wireless, enterprise, and industrial applications.
- Massive MIMO: It is another key technology being used in 5G deployment. It involves the application of MIMO technology on a much larger scale for greater network coverage and higher throughput and capacity gains promised by 5G.
- Machine Learning for Communication: Modern machine learning techniques provide ample opportunities to enable intelligent communication designs by addressing various problems such as signal detection, classification, and sparse signal recovery
- Design of Practical 5G Systems: My research in this area focuses on designing hardware and developing signal processing algorithms for mmWave- and massive MIMO-aided end-to-end 5G-new radio wireless systems using 3GPP standards.

NC 605: Mobile Computing (5G-Next Generation RAN Signaling) (July-Nov 2022)
Due to diverse use cases of 5G and beyond wireless systems, the requirements of a communication network are becoming more demanding (with respect to QoS and reliability, etc.).The networks over which the data traverses are becoming heterogeneous since communication devices cross through different versions of cellular networks (3G, 4G, 5G, beyond 5G and WiFi). This leads to complex signalling and system design for 5G and beyond wireless systems. Due to massive demand from customers/users, many companies are working to solve problems related to it.
This course offers a complete understanding of the 5G Next-Generation Radio Access Network (5G NG-RAN) Signallingof protocols implemented in the NG-RAN. The course presents the 5G architecture with its nodes, interfaces and protocol stacks and describes protocols through the functions and services they provide. The course focuses on the details of the NR interface signalling exchanged between the UE and the network. However, the most important aspects of other NG-RAN interfaces are also covered. Most important network procedures, such as signalling connection establishment, registration, service request and handover, are discussed and presented on signalling diagrams.

AI 833: Probabilistic Machine Learning (PML) (Jan-April 2022)
Objective: Probabilistic models for data are ubiquitous in many areas of science and engineering, and specific domains such as visual and language understanding, finance, healthcare, biology, climate informatics, etc. In machine learning, uncertainty comes in many forms. For example:
- We may want probabilistic predictions (e.g., probability that a transaction is a fraud)
- We may have imprecise/noisy data. Need to model the noise/uncertainty. Can do it using the appropriate pdf.
- Due to data scarcity, there may be uncertainty in the estimated model parameters and predictions. Thus, we may be interested in learning a probability distribution over parameters and predictions.
- Sequential decision-making: Estimate of model's uncertainty can “guide" us. For Example, given the current estimate of a function uncertainty over the input space, where should we acquire the next observation?
- Sometimes we may be interested in learning the underlying probability distribution of data. Learning the distribution can enable us to understand and also generate new data.
Prerequisite: Prior background in machine learning (ideally through formal coursework), and prior exposure to principles of probabilistic modeling. The students are expected to have strong foundations in probability and statistics, linear algebra, and optimization, and must also be proficient in programming in MATLAB or Python.
EC 303: Principles of Communication Systems (POC) (Jan-April 2022)

The students will learn about the required theoretical tools and engineering challenges in building such wireless communication systems. The students will also have an opportunity to do projects which will allow them to experiment on practical analog and digital communication systems.

5G Testbed Project
Before joining IIIT Bangalore, I worked in the EE department at IIT Kanpur as a Project Executive Officer on the Indigenous 5G Testbed Project funded by the Department of Telecommunications (DoT), Govt. of India. The project aims to build an end-to-end testbed that closely resembles a real-world 5G deployment including enhanced mobile broadband (eMBB), Ultra low latency communication (URLLC) and Massive machine type communication (mMTC), both in sub 6 GHz and millimeter wave frequency (24.25 GHz to 52.6 GHz) bands. The 5G Testbed hardware is divided into two parts: a remote radio head (RRH) unit and a baseband unit (BBU, which communicate to each other using a highspeed optical fronthaul link. My key contributions for the 5G testbed projects are as follows.
BBU Hardware Design and Testing
The BBU consists of an FPGA based baseband card and a server, which communicate using a PCIe interface. We designed FPGA based baseband card with PCIe form-factor by collaborating with the industries. The baseband card, whose bird eye view is shown below, performs physical laying baseband signal processing at the 5G testbed base station. Nine such baseband cards sit in a server. One server can control nine RRH units (equivalent to 3 cell sites). One BBU can control three cell sites, and if we have to control more cell sites, we can keep stacking multiple servers in a server rack. I also performed complete testing of the baseband card after fabrication.
Fig: Baseband Card (Bird Eye View)
Design and Testing of 3GPP Complaint Control and Data Channels for 5G-NR
We designed physical layer signal processing algorithms for the control and data channels, namely PDCCH (physical downlink control channel), PUCCH(physical uplink control channel), PDSCH (physical downlink shared channel) and PUSCH (physical uplink shared channel), using the 3GPP standards (release 15) for 5G-New Radio. The algorithms were designed using Vivado HLS (Xilinx’s high-level synthesis tool) and benchmarked with their respective MATLAB chains, both before and after implementing on the hardware. Various signal processing blocks of the PDSCH, PDCCH and PBCH transmit chains at the base station are shown below.
I am looking for motivated students interested in working on state-of-the-art problems in 5G and next-generation wireless communications systems. There are no specific prerequisites, please send me an email with your resume, if interested. Please see Research/Publications/Cunsultency tabs for more details.
