The Implementation of Time_domain Channel Estimation on FPGA |
| |
Abstract: | In multipath communication systems,real_time and accurate channel information is the key point to channel equalization and data detection.This paper,by using the good cyclic autocorrelation of the training sequence(PN sequence),estimates the channel time_domain response,and implement it in the FPGA. |

Keywords: | PN sequence correlation time_domain channel estimation FPGA |
