针对多天线系统,研究了基于导频的迫零算法信道估计技术。该技术在典型的室内和室外(车载)通道进行测试。性能结果的误码率,均方误差和数据吞吐量。据发现,不同的试点战略提供了最好的性能在每一个环境中,因此,应考虑自适应系统。
A number of pilot-based channel estimation techniques are investigated for a multiple antenna system using the zero-forcing algorithm. The techniques are tested in typical indoor and outdoor (vehicular) channels. Performance results are presented in terms of bit error rate, mean squared error and data throughput. It is found that different pilot strategies offer the best performance in each environment, and hence an adaptive system should be considered.
