  • Fast fourier transform processors, methods and orthogonal frequency division multiplexing receivers including memory banks
    Patent number: 7804905
    Abstract: A signal converter having a memory bank and radix-2 Fast Fourier Transform (FFT) transforms an Orthogonal Frequency Division Multiplexing (OFDM) signal having a long preamble and data into an OFDM signal in the frequency domain, and outputs the transformed OFDM signal. The radix-2 FFT has a linear systolic array architecture, transforms the long preamble stored in the memory bank by FFT, then stores the transformed long preamble into the memory bank, transforms data input through a buffering process and data input directly by FFT, and stores the transformed data in the memory bank. The memory bank has four memories, stores the long preamble transformed or not transformed and outputs the stored long preambles or the transformed data for the purpose of demodulation as the transformed data is input. Data-processing delay and/or power consumption may be reduced during the operation of the FFT processor.
