摘要
Abstract
Chirp signals have the best energy concentration in a special fractional Fourier domain.A BOK-Chirp spread spectrum communication scheme based on fractional Fourier transform ( Frft) is proposed. The Chirp signals are modulated by binary orthogonal keying signals at the transmitting end,and they are detected through Frft at the receiving end.Simulation shows that the scheme has good performance in bit error rate.关键词
