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 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, generating a third waveform using at least the first and third set of phase and amplitude differences, and converting the third 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 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; 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; generating a third waveform using at least the first and third set of phase and amplitude differences; and converting the third waveform from the frequency domain to the time domain. |
