AI Technical Summary
The existing power line carrier communication receiver uses a radix-4 FFT data processing method, which results in a long data acquisition cycle and fails to meet the timeliness requirements of data processing.
By polling and distributing the data in the discrete data sequence to four single-port read/write memories, calculating the number of iteration layers and butterfly operation groups of the radix-4 FFT, adjusting the data storage address index, and using the circular right shift value for dynamic mapping, the four single-port read/write memories can be accessed in parallel within one clock cycle to obtain the data to be processed.
It improves the data parsing speed of the power line carrier communication receiver, ensures the quality and rate of power line carrier communication, and enables timely acquisition of the frequency components of each subcarrier signal in the received signal.
