Performance Analysis of M-ary Multi-Orthogonal Keying

Modulation-hopping (MH) system is a new kind of communication system. In order to meet the needs of MH system in various kinds of modulations and a common frame, m-ary multi-orthogonal keying (MMOK) is presented in this paper. The performance of MMOK on multipath fading channels is evaluated in term of average SNR for both the symbol error probability and bit error probability. We adopt Channel Matched Filter (CMF) to remove the multipath channel effects. Numerical results show MMOK has special performance on multipath fading channels. It concludes that MMOK can be applied in higher data transmission to perfect performance and improve bandwidth efficiency, which is beneficial to many systems.
