Abstract: A method for processing data based on 3072-point Fast Fourier Transform (FFT) and a processor based on 3072-point FFT are provided. The method for processing data based on 3072-point FFT includes: storing 3072-point data into a data storage module according to a predetermined mapping relationship (101); reading 16 data in parallel from the data storage module for performing 3-point DFT operation, and storing results into the data storage module in situ after completion of the operation (102); and reading 32 data in parallel from the data storage module for performing 1024-point DFT operation and storing results into the data storage module in situ after completion of the operation until the FFT of 3072-point data is completed (103).

Abstract: Disclosed are an IQ mismatch compensation method and apparatus for a radio frequency communication system, a compensation device and a communication device. The method comprises: acquiring an interaction result of test signals between a transmitting component and a receiving component; obtaining angle mismatch parameters of a pre-determined type according to the interaction result; determining a frequency domain compensator for performing mismatch compensation on the frequency-dependent angle mismatch parameters according to the following formulae: Y(w)=X(w)−jP(w)*X*(−w) and Y(−w)=X(−w)+jP(w)*X*(w); and performing frequency domain compensation on the frequency-dependent angle mismatch parameters by using the frequency domain compensator. Also disclosed is a computer storage medium.
