This paper analyzes the structure and modem scheme of chirp-BOK system. In additive white Gaussian noise channel, an approach of studying the performance of chirp-BOK is presented and the BER-SNR result is evidently improved compared with traditional BOK. Furthermore, the BER of multi-user chirp-BOK system is discussed.
