摘要： Method and system encodes a signal according to a code rate that includes a ratio of uncoded bits to coded bits. An outer Reed-Solomon encoder encodes the signal into codewords. An interleaver converts the codewords into bits of frames 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. The convolutional code is punctured and code states are added by the inner encoder to improve the code rate.

摘要： A method of communicating data to M receiving antennas from N transmitting antennas, where M and N are integers and unequal, has the steps of sending a message to determine a number of transmit paths to be used, awaiting an acknowledgement message comprising a number of receiver paths, setting the number of transmit paths based on at least the acknowledgement message, producing data streams from outbound data based on the number of transmit paths, applying the data streams to a space/time encoder to produce encoded signals and transmitting the encoded signals from at least a portion of N transmitting antennas.

摘要： Methods and systems for choosing at least one signal path are disclosed. Aspects of the method may include determining a signal quality metric for each of a plurality of signal paths, modifying the signal quality metric for each of the plurality of signal paths, and selecting at least one signal path based on at least one modified signal quality metric. At least one of the signal paths may be cycled through and the signal quality metric may be biased and/or increased and/or decreased for each of the plurality of signal paths by a fixed amount and/or by a predetermined amount. The signal quality metric may also be dynamically changed for each of the plurality of signal paths.
