Abstract

Based on adaptive theory, an Adaptive Modulation and Coding (AMC) Multiple Input Multiple Output (MIMO) system with adaptive Turbo receiver is designed to increase the overall capacity and decrease the processing delay. The scheme sets several factors including channel coding rate, modulation mode and iteration times of Turbo receiver as adjustable elements. To guarantee the superiority of the proposed adaptive Turbo receiver in terms of decreasing processing delay and power consuming, an MMSE based no-ordered parallel soft interference cancellation (NOPSIC) MIMO detector which takes error propagation into account is explored for the non-first iteration. Simulation results reveal that the proposed scheme could significantly raise the system capacity, meanwhile bring down overall times of iteration processing by nearly one third.
