摘要

本文介绍了利用NRZ编码器获得的一种新的导频模式。通过在MIMO-OFDM中使用所提出的NRZ编码导频进行半盲信道估计(其中信道响应通过插值后续信道估计获得)，降低了中等变化信道的均方误差并降低了复杂度。与基于导频的信道估计相比，该方法充分利用了带宽，并通过精确的信道估计提高了系统性能。

NRZ encoded pilots for Semi Blind Channel estimation

This paper introduces a new pilot pattern which is obtained by using NRZ Encoder. By using the proposed NRZ Encoded Pilots for Semi Blind Channel estimation (in which the channel response is obtained by interpolating the subsequent channel estimations) in MIMO-OFDM, reduces the Mean Square Error for moderately varying channels and reduces complexity. This method perfectly utilizes the bandwidth and improves the system performance by accurate channel estimation compared to pilot based channel estimation.
