C fixed-point implementation of codecs for WiSiG networks.
C fixed-point implementation of a turbo-like code for ORB Analytics, USA.
Design and FPGA implementation of an OFDM modem for troposcatter communications for DEAL, Dehradun. This is done jointly with Profs. Radhakrishna Ganti and Nitin Chandrachoodan.
Design of a link enhancer that works at the link layer of an E1 link for BEL, Bangalore.
Assistance with design and implementation of various codes (LDPC/Turbo/BCH etc) that appear in the DVB standards worldwide. This work is for Saankhya Labs, Bangalore.
C fixed-point implementation for layered decoding of a generic LDPC code for ORB Analytics, USA.
Design and C implementation of LDPC codes for a very low frequency (VLF) communication system for DEAL, Dehradun, India. Block synchronization at very low SNRs is part of this ongoing project.
C fixed-point implementation of JPL's AR4JA LDPC codes for ORB Analytics, USA.
Design and C fixed-point implementation of a LDPC code for a wireless OFDM system was completed for Radiospire Inc, Boston, USA. Modifications of the standard CRC-based error detection were proposed and analyzed as part of this consultancy.
This work was done during doctoral research for Calimetrics Inc, USA.
Several lectures have been delivered in companies and university departments on the areas of basic digital communications, error control coding, turbo codes and LDPC codes. The codes in the leading standards are described as part of the training.
