Abstract:
1. A method, comprising: receiving a multiple-carrier signal having periodic control packets, wherein each bit of a control packet is redundant on a plurality of the carriers; determining bit loading information and signal-to-noise ratios (SNRs) of the carriers; initializing a standby mode bandwidth to encompass a subset of carriers of the multiple-carrier signal, including at least one carrier of each information bit of a control packet; combining redundant carriers within the subset of carriers; adjusting the standby mode bandwidth until SNRs of carriers and combined carriers within the subset of carriers are sufficient to recover the control packets from the subset of carriers; and demodulating the multiple-carrier signal, including demodulating the bandwidth of the multiple-carrier signal in an operational mode, and demodulating the standby mode bandwidth of the multiple carrier signal in a standby mode to recover control packets from the subset of carriers in the standby mode, and further including,
