Research Interests:

 

Currently, I am working on reduced complexity symbol detection for wireless communication systems employing OFDM

technology in conjunction with symbol spreading for enhanced performance in multipath propagation.

 

Other interests that are incorporated in the current work are

 

 

Specific applications that we are working on are LTE standard for 4G wireless and MIMO-OFDM systems.

Examples of the some of the algorithm:

·         Implementation of Branch & Bound (BB)  Algorithm for MIMO-OFDM signal detection.

·         Combination of BB and M algorithm for MIMO with higher QAM constellation.

·         Implementation of low complexity BB search tree for code spread OFDM system.

·         Turbo MMSE Equalization for Spread OFDM signal Decoding.
