摘要

Probability-based clipping of full parallel 128-point FFTs is proposed, which offers 3-bit resolution reductions of FFT and achieves 28% logic resource usage reduction and highly accurate stage-dependent bit resolution maps. Results are verified over FPGA-based Coherent Optical OFDM transmission systems.
