Biorthogonal multicode modulation for high-rate high-reliability personal communications requiring controlled peak-to-average transmit power ratio

A modulation scheme is proposed for high-information-rate high-reliability personal communications where controlled peak-to-average transmit power ratio is an issue. The scheme is a hybrid of classical biorthogonal modulation and code division multiple access multicode modulation. Analytical and simulation results are presented for static AWGN channels and simulation results are presented for flat fading channels.
