CDMA, multichannel, M-ary keying, MBOK, orthogonal


The new method of Multichannel M-ary Bi-Orthogonal Keying, its operating principle and performance studying are introduced in this paper. Utilized spectral efficiency and BER performance of this method are also studied in comparison with DS-CDMA. Overall efficiency as spectral-to-power efficiencies rate comparison of these multichannel CDMA techniques is presented. All theoretical issues are accompanied with simulation results in MATLAB software package.
