Algorithms for coherent diversity combining of M-ary orthogonal signals.

Algorithms for coherent diversity combining of M-ary orthogonal signals.

This paper discusses the use of coherent demodulation for antenna array receivers employing direct sequence spread spectrum techniques and M-ary orthogonal modulation. Three different approaches are discussed. The first is a conventional receiver using training sequences and decision feedback for ch...
