摘要

我们开发了一种分析方法来评估在时分双工(TDD)模式下工作的多发射天线系统的Tomlinson-Harashima预编码(THP)的符号误码率(SER)。通过小误差假设，对给定信道估计误差引起的噪声进行了深入的研究，从而可以计算出具有信道估计误差的SER。

The effects of channel estimation on Tomlinson-Harashima precoding in TDD MIMO systems

We develop an analytical method to evaluate the symbol error rate (SER) of Tomlinson-Harashima precoding (THP) for a multiple transmit antenna system operating in a time division duplex (TDD) mode. By making small error assumption the noise due to the channel estimation error for a given channel is investigated thoroughly, which enables one to calculate the SER with channel estimation error.
