Abstract :
A SIC architecture with asynchronous bit-serial PEs is presented and applied to the Sande-Tukey´s FFT. The resulting architecture can easily be modified for higher throughput and/or lower power consumption. Using this architecture a high-performance chip for use in an OFDM transmission system has been designed
