Orthogonal frequency division multiplexing (OFDM) channel estimation to improve the smoothing process

摘要

A method of processing communication signals, is described. The method includes receiving a communication signal in a time domain, converting the communication signal to a frequency domain, providing resource blocks, the resource blocks including a first resource block and a second resource block, the first resource block 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, providing a first waveform based on the resource blocks and the third resource block, applying a smoothing filter against the first waveform to generate a second waveform, and converting the second waveform from the frequency domain to the time domain.

1. A method of processing communication signals, the method comprising:
receiving a communication signal in a time domain; converting the communication signal to a frequency domain; providing a plurality of resource blocks based on the communication signal in the frequency domain, the plurality of resource blocks, being arranged from left to right, including a first resource block and a second resource block on the right side of the first resource block, the first resource block having a first boundary on the right edge thereof and a second boundary on the left edge thereof, 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 one or more pilot signals; generating a third resource block based on the one or more pilot signals; providing a first waveform based at least on the plurality of resource blocks and the third resource block; applying a smoothing filter against the first waveform to generate a second waveform; and converting the second waveform from the frequency domain to the time domain.
