| 摘要 |
The invention provides a method and device for filtering orthogonal frequency division multiplexing (OFDM) channel estimate result, to solve the problems in the prior art that for channel estimate result filtering the realization is complex or the performance is poor. By embodiments the following method is described: transforming time domain synchronous symbols received by the terminal equipment to frequency domain synchronous symbols; computing frequency domain impulse response sequences based on the frequency domain synchronous symbols; adjusting least mean square (LMS) adaptive filter coefficients based on the frequency domain impulse response sequences; obtaining coefficients of the data symbol channel estimate result frequency domain filter based on the coefficients obtained from said adjusting; filtering the OFDM channel estimate result by using the data symbol channel estimate result frequency domain filter. The corresponding device is disclosed by the embodiments. There is less computation, simpler realization and better filtering performance provided with the OFDM channel estimate result frequency domain filter obtained from the technical solution of the present invention.
