Patent ID: 8254498

Claim:
A method for receiving signals in a multiple access communication system comprising: receiving, at a receiver, a first modulated signal on a first sub-channel, wherein a first transmitter randomly selects the first sub-channel from a plurality of sub-channels; receiving, at the receiver, a second modulated signal on a second sub-channel, wherein the second sub-channel is orthogonal to the first sub-channel, wherein a second transmitter randomly selects the second sub-channel from the plurality of sub-channels, and wherein at least a portion of the first signal overlaps with a portion of the second signal; storing, for each of the plurality of sub-channels, a plurality of potential symbols in a buffer; determining a plurality of potential data frames based upon the potential symbols in the buffer; and applying a signal detection algorithm to the potential data frames to detect the first modulated signal and the second modulated signal.
