Summary:In recent years, iterative receiver has been widely considered since it is able to achieve high data rates and reliable communications for coded MIMO-OFDM systems. However, such a receiver is extremely challenging in practical implementation. In this paper, we present an efficient fixed-point arithmetic of iterative receiver based on low-complexity K-Best decoder in order to reduce the hardware costs in terms of area and execution time. The performance of fixed-point receiver is then evaluated with different modulation orders and channel models. Moreover, a testbed for MIMO-OFDM system using wireless open access research platform (WARP) is introduced in order to evaluate the performance of the receiver under real system conditions.
