Abstract: A signal quality metric is determined for each of multiple signal paths. Each of the signal paths corresponds to a respective antenna. The determined signal quality metric is modified for one or more signal paths. A subset of the signal paths is selected for receiving a signal based at least in part on the determined signal quality metrics. The selecting is biased based at least in part on the modified signal quality metrics.

Abstract: Method and system encodes a signal according to a code rate that includes a ratio of uncoded bits to coded bits. An outer encoder encodes the signal into code words. An interleaver converts the code words into a byte sequence for wireless transmission. An inner encoder executes a convolutional code to generate an encoded signal. The encoded signal is transmitted over a plurality of subcarriers associated with a wide bandwidth channel having a spectral efficiency associated with the code rate. The outer encoder includes a Reed-Solomon encoder having a rate that increases the code rate of uncoded bits to coded bits.

Abstract: A network device for implementing high-rate greenfield transmission in a mixed mode frame structure. The network device is configured to transmit a mixed mode frame on two adjacent channels. The mixed mode frame comprises at least two backward compatible portions of a first frequency and a greenfield portion of a second frequency.
