A receiver for detecting spread spectrum binary data particularly on a power line in the presence of channel distortion. In one embodiment a standard pattern ideally suited for minimal distortion in the channel is used in conjunction with an alternate pattern which is developed to better detect carrier...http://www.google.fr/patents/US5937003?utm_source=gb-gplus-shareBrevet US5937003 - Adaptive reference pattern for spread spectrum detection claims
