Claim:
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 including a first resource block and a second resource block; selecting a first plurality of pilot signals from the first resource block and a second plurality of pilot signals from the second resource block; calculating a first average value based on all of the first plurality of pilot signals; calculating a second average value based on all of the second plurality of pilot signals; determining a phase difference between the first plurality of pilot signals and the second plurality of pilot signals using the first average value and the second average value; adjusting a first phase of the first resource block using the phase difference; providing a first waveform using the first resource block with adjusted first phase and the second resource block; applying a smoothing filter against the first waveform to generate a second waveform; generating a third waveform using at least the second waveform and a set of phase and non-zero amplitude differences; and converting the third waveform from the frequency domain to the time domain.
