On performance of FEC in E-SDM

摘要

In multiple-input multiple-output channels, channel capacity is highly improved by eigenbeam space division multiplexing (E-SDM), when the channel response is known at a transmitter. In this paper, we introduce FEC (turbo codes, in specific) to the E-SDM and evaluate its performance. Computer simulations show the results on performance improvement due to coding gain. However, the improvement is larger in the SDM case. Thus, the performance of E-SDM and SDM becomes very close.
