【 摘 要 】

References(3)An area and power efficient signal reordering unit (SRU) for OFDM systems that reorders the bit-reversed output of an FFT unit into linear order is proposed. By using a FIFO that is smaller than an N-word memory used in conventional SRUs, the proposed SRU achieves about 25% reductions in both the area and the power consumption in case of a 1024-point FFT.
