摘要 概述了TCM旋转不变码的原理、设计思想及性能。并针对8psk调制介绍了一种90°旋转不变码的计算机搜索算法。对搜索出的旋转不变码进行了性能仿真。 This paper generally discusses the c oncept and design rules of rotationally invariant codes(RIC).A simple search algorithm based on 8psk for 90-rotationally -invariant feedforward trellis codes is present.In addition,we report th e performance simulation results fo r RIC in an AWGN channel.
