Abstract :
A multi-stage multi-user detection (MUD) scheme designed for a fast-FH/MFSK system is proposed, in which the received signal level is attenuated by a constant scaling factor when the signal is deemed to be overwhelmed by multi-user interference. In the investigated scenario a substantially reduced bit error rate is achieved.
