Abstract :
In this paper a novel implementation is presented for an on-line FFT network, using complex on-line arithmetic, based on adopting a redundant complex number system (RCNS) to represent complex operands as a single number. We present cost comparisons with alternative approaches, to demonstrate a significant improvement in design for FPGA´s.
