摘要： In a wireless communication apparatus of multi-input system, Fourier transform is used to estimate the frequency response of a received signal and further provide a converted impulse response of time domain, and a window function having a simple lowpass filter characteristic is used to separate the impulse response into channel impulse responses of the respective signals. The window function having the lowpass filter characteristic is relatively simple in arithmetic and receives less influence from the channel statistical characteristic, so that it can realize both a separation of multi-antenna channel impulse responses and a highly-precise channel estimation at the same time.
