ABSTRACT:
A communications system is set forth comprising a plurality of remote receivers numbering M for receiving and demodulating respective PSK symbols received from a transmission medium. A central transmitter transmits periodically occurring frames of data to the plurality of receivers over the transmission medium. Each frame of data contains L total symbols including a subset of X.sub.m symbols designated for each one of the M plurality of remote receivers. The transmitter interleaves the X.sub.m symbols in a given frame into a plurality of periodic, non-consecutive groups of R symbols per group, wherein R<X.sub.m. In accordance with one embodiment of the invention, each of the remote receivers includes an equalizer implemented as a digital filter having N taps. In such instances, the transmitter interleaves the X.sub.m symbols in a given frame into a plurality of periodic, non-consecutive groups of R symbols per group, wherein R.ltoreq.N.
