Channel estimation method for overcoming channel discontinuity between sub-bands of an orthogonal frequency division multiplexing (ofdm) system

摘要

A method 300 of processing signals. The method includes receiving a communication signal in a time domain 302, converting the communication signal to a frequency domain 304, providing resource blocks based on the communication signal in the frequency domain 306, the resource blocks including a first resource block and a second resource block, selecting pilot signals from the first resource block and pilot signals from the second resource block 308, determining a first set of phase and amplitude differences among the pilot signals 310, determining a second set of phase and amplitude differences among the pilot signals 312, determining a third set of phase and amplitude differences between the pilot signals and the pilot signals 314, generating a first waveform using at least the first and third set of phase and amplitude differences 316, applying a smoothing filter against the first waveform to generate a second waveform 318, and converting the third waveform from the frequency domain to the time domain 322.
