The Comparison between Space-time Blocks Codes and Trellis Codes under Maximum Likelihood Sequence Estimator
In multiple input and multiple output (MIMO) system, the channel code is very important and complex compare single antenna system. Space-time codes (STC) were proposed to solve the problem. In space-time codes family the space-time block code and space-time trellis code are applied in many cases. In this paper we proposed the maximum likelihood detector used in space-time trellis codes system, and compare the difference between these two kinds of codes under maximum likelihood sequence estimator, get which situation is better to these two kinds of STC.
