Analysis and study of channel estimation on performance effect of linear zero forcing receiver

This paper analyzes the effect of channel impulse response estimation on the performance of linear zero forcing receiver. Four noise reduction schemes based on maximum path power and noise power respectively have been considered and the computer simulation results show their performance. At the same time, they are compared to the theoretical derivation. Both simulation and analysis show that by improving the estimation accuracy of channel impulse response, the system performance of the linear zero forcing receiver could be improved.
