摘要：

This paper proposes and studies a novel M-ary chirp modulation scheme adopting quasi-orthogonal waveforms. The Symbol error probability(SEP) of M-ary modulation over Additive white Gaussian noise(AWGN)channel is derived based on coherent detection, which is a function of modulation factor and waveform period.Moreover, the SEP is investigated over a channel limited by a nominal bandwidth. Both theoretical analysis and simulations prove that the SEP performance of the proposed 8-ary chirp modulation outperforms that of conventional 8 Phase shift keying(8PSK) with the same bandwidth efficiency.
