When code-division multiple access (CDMA) signals are linearly multiplexed (phase-coherently summed) at a transmit terminal, a receiver demodulating information from one component signal experiences multiple access interference (MAI) from all others to the extent that the waveforms are not strictly orthogonal. Under a model for which: (1) the users are homogeneous, i.e., identical in those parameters...
CDMA systems transmitting multiple signals from a single source normally employ linear superposition of codes. The resulting signal has a high peak-to-average power ratio (PAPR), which is undesirable from a high power amplifier (HPA) viewpoint. Several techniques have been proposed to reduce PAPR and ease the HPA requirements. Among these, constant-envelope CDMA (CE-CDMA) is an alternative that eliminates...
