Single Parity Check Product Code in MB-OFDM Ultra Wideband System

摘要

In ultra wideband (UWB) system, multiband orthogonal frequency division multiplexing (MB-OFDM) has been proposed to provide high-speed transmission for short-range wireless links. In this paper, 2 dimensional (2D) single parity check product code (SPCPC) is investigated in MB-OFDM UWB communication for Rayleigh fading channel and additive white Gaussian noise (AWGN) channel in order to improve the error performance. The encoder and parallel decoder of the 2D-SPCPC are explained. It is shown that the proposed model may provide significantly better error performance compared to the conventional MB-OFDM at low SNR, but with complexity tradeoff.
