In this paper, we present a low power and variable-length design of fast Fourier transform (FFT) processor for flexible MIMO-OFDM applications. In this work, mixed-radix-2/4/8 algorithm and new continuous-flow method are applied to achieve variable-length of 1K/2K/4K/8K points and in-order output. Furthermore, ping-pong cache memory architecture and optimized data scaling strategy are also applied to reduce main memory accesses up to 50% and achieve higher SQNR requirements of 16/64-QAM signals… CONTINUE READING
