Abstract :
In this paper, we propose a linear probabilistic data association (PDA) based signal detector for V-BLAST. The main idea is to utilize the principle of a pre-whitening filter to realize single symbol detection, similar to virtual single input and single output (SISO) system, by removing the effects of past decisions. Simulation results show that our scheme can provide performance very close to ML decoding with extremely low computational complexity.
