Abstract :
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 2DSPCPC 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.
