Performance Analysis of a Constant-Amplitude Multi-Code-Bi-orthogonal Modulation

In this paper, a constant-amplitude bi-orthogonal multi-code (CABM) modulation is proposed. The bit error rate (BER) performance expressions and the union bounds of the proposed CABM modulation and demodulation pairs are derived analytically. The results of the computer simulation and theoretical analysis performed show that the BER performance of the proposed CABM modulation is significantly better than that of a CAOM modulation.
