分析了信道冲激响应估计对线性迫零接收机性能的影响。考虑了一种基于最强径功率和三种基于噪声功率估计的域值方法并且用计算机对比它们的仿真性能。同时,还进行了理论分析。计算机仿真结果和理论分析同时表明通过去除噪声的影响,提高信道冲激响应估计精度,可以提高线性迫零接收机的系统性能。
The influence of channel impulse response estimation on the performance of linear zero-forcing receiver is analyzed. A threshold method based on the strongest path power and three noise power-based estimates was considered and their simulations were compared using a computer. At the same time, also conducted a theoretical analysis. Computer simulation results and theoretical analysis also show that by removing the influence of noise and improving the estimation accuracy of channel impulse response, the system performance of linear zero-forcing receiver can be improved.
