Abstract: A device includes a signaling interface to receive OFDM signaling for an OFDM channel from multiple transmit nodes, an OFDM receiver to process the OFDM signaling, and a channel allocation module. The channel allocation module allocates subchannels of the channel among transmit nodes by: determining, for each transmit node, a corresponding SNR for each of the subchannels; assigning to each transmit node a corresponding subset of buckets of a set of buckets, the number of buckets in the subset based on a data rate requirement of the transmit node; distributing subchannels among the buckets based on the SNRs of the subchannels; and, for each transmit node, allocating to the transmit node the subchannels distributed to the subset of buckets assigned to the transmit node. The device further includes an OFDM transmitter to transmit configuration information to the transmit nodes, the configuration information representing the allocation of the subchannels.

Abstract: A carrier tracking technique includes allocating a first number of bits per symbol to a carrier tracking subcarrier of a plurality of subcarriers of an orthogonal frequency division multiplexing (OFDM) signal based on a first target performance margin. The technique includes allocating numbers of bits per symbol to other subcarriers of the plurality of subcarriers based on a second target performance margin.
