A parallel DFT processing method for digital RF memory system

Presents a fast parallel DFT processing method to improve the processing speed of the time division multiplexing digital RF memory (DRFM) system. The corresponding parallel DFT processing algorithm is derived according to the characteristics of the storage structure of the time division multiplexing system and a structure with minimum quantity of plural operation is obtained by analyzing the algorithm, thus realizing a high and super-high speed real-time signal processing of DRFM which will be helpful in the design of DRFMs.
