Abstract

Currently, low-density parity check (LDPC) coded multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) systems becoming very important research area in wireless communication. Especially in high throughput wireless communication, due to its capacity increasing ability in a wireless fading environment. And also it is one of the research candidates for 5G communication when it is applied in large scale MIMO systems. It has been shown that LDPC coded MIMO systems have much attention in industrialization by some development work from its theory to commercial products in the semiconductor industry. And in this paper, we applied Expectation Propagation (EP) algorithm with A message-passing algorithm (MPA) and belief propagation (BP) decoding for LDPC coded MIMO-OFDM systems. In fact, Expectation Propagation (EP) algorithm is a low-complexity algorithm. It solves the posterior marginalization problem easily which it makes efficient work with high-dimension MIMO. Therefore, our proposed work is for high throughput providing channel coding in the high- dimension wireless channel.
