Patent ID: 8406425

Claim:
In a system for transmitting data over a plurality of co-channels, a method of communicating a first frame on a first co-channel of the plurality of co-channels and a second frame on a second co-channel of the plurality of co-channels, comprising: generating a first sequence according to a first seed; generating a second sequence according to a second seed different than the first seed; encoding a payload of the first frame using Low Density Parity Check (LDPC) coding; scrambling the first frame according to the first sequence and scrambling the second frame according to the second sequence; transmitting the scrambled first frame at a first time over the first co-channel from a transmitter; and transmitting the scrambled second frame at a second time over the second co-channel from the transmitter; wherein the first time is equal to the second time and the first seed and the second seed are selected to reduce cross-correlation between the first frame and the second frame.
