This paper investigates the performance of multiple- input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) systems using different wideband MIMO channel models. The considered MIMO channel models are based on the geometrical elliptical model and the geometrical one-ring model. The spatial correlation effects due to the limited antenna spacings and the Doppler effect caused by...
This paper investigates fountain codes and applications to wireless broadcast. In this paper, we extend fountain codes on erasure channels to arbitrary channel types by first taking into account the symbol information and belief propagation (BP) algorithm. We propose a rateless-coding framework based on fountain codes, which allow reliable wireless broadcast communications and asynchronous data access...
