Abstract :
Multi-user interference induces performance loss in terms of BER and channel capacity when present in a communication system. Nevertheless multi-user interference can be suppressed via signal processing techniques so to improve performance. In fact, the presence of this interference reduce the channel capacity region A. Carleial et al., (1975). In this work the conditions allowing perfect interference cancellation are derived so to arrive at the same capacity region of an interference-free network.
