- W977097255 abstract "针对频率选择性衰落信道下2发1收STBC—SC-FDE系统收发两端的信号编码与处理结构，应用系统的频率域输入一输出模型，设计了一种最小二乘信道频率响应（Channel frequency response，CFR）估计算法。对算法均方误差的分析表明，采用Chu序列作为最优训练序列不仅能够实现CFR估计的最小均方误差，而且能保证系统具有比较低的峰均功率比（Peak-to—average power ratio，PA／PR）。该算法相比那些先估计信道时域响应（Channel impulse response，CIR）再转换为CFR的方法能够节省更多的计算资源。最后Monte Carlo仿真验证了该算法的性能。" @default.
