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

A system for processing communication signals, the system comprising:

• a memory device;
• and
• a computer processor in communication with the memory device, wherein the memory device includes sets of instructions when executed by the computer processor, cause the computer processor to:
• receive a communication signal in a time domain;
• convert the communication signal to a frequency domain;
• provide 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, 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 one or more pilot signals;
• generate a third resource block based on the one or more pilot signals;
• provide a first waveform based at least on the plurality of resource blocks and the third resource block;
• apply a smoothing filter against the first waveform to generate a second waveform;
• generate a third waveform using at least the first and third set of phase and amplitude differences;
• and
• convert the third waveform from the frequency domain to the time domain.

A computer-readable medium for processing communication signals, the computer-readable medium having sets of instruction stored thereon which, when executed by a computer cause the computer to:

• receive a communication signal in a time domain;
• convert the communication signal to a frequency domain;
• provide 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, 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 one or more pilot signals;
• generate a third resource block based on the one or more pilot signals;
• provide a first waveform based at least on the plurality of resource blocks and the third resource block;
• apply a smoothing filter against the first waveform to generate a second waveform;
• generate a third waveform using at least the first and third set of phase and amplitude differences;
• and
• convert the third waveform from the frequency domain to the time domain.
