摘要
介绍了多路径信号建模技术,采用最小二乘法从接收的多路径信号中估计直达信号和各种反射信号的到达时间、频率、幅度、相位等各种参数。
The muhipath signal modeling technology is introduced. Using the least-square algorithm, parameters such as the reaching time, frequency, amplitude, and phase of the direct and reflection signals are estimated from the receiving muhipath signals.
