|Abstract:||In this paper, we propose a sequential Monte Carlo (SMC) symbol detector for differentially encoded multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) systems. We first propose the periodic termination of differential phase trellis and it is seen that this method yields advantages that allow us to simplify the pilot-aided SMC detector. Specifically, the resampling step that is present in conventional SMC methods is circumvented, and the multi-dimensional distribution required for sequence imputations reduces to a simple product of one-dimensional likelihood functions and a priori probabilities that are easily obtained from the decoder. This non-resampling SMC detector is applied to both convolutional-coded and low-density parity check (LDPC)-coded MIMO-OFDM systems and simulation results suggest the promising performance of our proposed detector. © 2005 IEEE.|
