Abstract:
1. In a system for transmitting data over a plurality of signals, each signal associated with one of a plurality of co-channels defined at least in part by a frequency band allocated to each respective co-channel, a method of communicating a first frame on a first co-channel of the plurality of co-channels on a first signal of the plurality of signals and a second frame on a second co-channel of the plurality of co-channels on a second signal of the plurality of signals, comprising: generating a first sequence according to a first seed; generating a second sequence according to a second seed different than the first seed; scrambling at least a portion of the first frame according to the first sequence and scrambling at least a respective same portion of the second frame according to the second sequence; transmitting the first signal at a first time over the first co-channel the first signal comprising the scrambled first frame; and transmitting the second signal at a second time equal to the first time over the second co-channel, the second signal comprising the scrambled second frame; wherein the first seed and the second seed are selected to reduce cross-correlation between the first frame and the second frame.
