Estimation du canal de multiplexage par répartition orthogonale de la fréquence (ofdm) pour améliorer le processus de lissage

摘要

A method 300 of processing communication signals, is described. The method includes receiving a communication signal in a time domain 302, converting the communication signal to a frequency domain 304, providing resource blocks, the resource blocks 306 including a first resource block and a second resource block, the first having a first boundary and a second boundary, the first boundary being adjacent to the second resource block, the second boundary being non-adjacent to other resource blocks, the first resource block including pilot signals, generating a third resource block based on the one or more pilot signals 308, providing a first waveform based on the resource blocks and the third resource block 310, applying a smoothing filter against the first waveform to generate a second waveform 312, generating a third waveform using at least the first and third set of phase and amplitude differences 314, and converting the third waveform from the frequency domain to the time domain 316.
