摘要

In this paper, M-ary Quaternary Orthogonal Keying modulation (MQOK) is proposed based on the analysis of Complementary Code Keying (CCK) and Mary Bi-orthogonal Keying (MBOK). Besides, CCK can be defined as a kind of MQOK. By analyzing the performance of MQOK on the condition of additive white Gaussian noise (AWGN) channel, new closed-form formulae for CCK modulation are gained. Comparison between the numerical result and the simulation result confirms that these formulae are more accurate and practical to manipulate.
