Abstract :
The performance of some channel overloading schemes based on using two sets of orthogonal signal waveforms is investigated on a Rayleigh fading channel. The achievable overload factor is evaluated for quaternary phase-shift keying (QPSK) modulation. It is shown that when used in conjunction with soft iterative interference cancellation, the investigated channel overloading techniques offer substantial channel overloads without requiring any user sorting according to the fading amplitudes.
