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： The present invention provides adjusting of a radio frequency (RF) receiver that includes processing that begins by enabling an initial setting of the RF receiver, wherein the initial setting is based on a bandwidth of a channel of a plurality of channels. The processing continues by receiving an RF signal containing a preamble of a frame via one of the plurality of channels. The processing continues by converting the RF signal to a baseband signal based on the initial setting. The processing continues by determining channel type of the one of the plurality of channels based on the baseband signal. The processing continues by determining whether the channel type corresponds to the bandwidth of the initial setting. The processing continues by, when the channel type does not correspond to the bandwidth of the initial setting, adjusting setting of the RF receiver based on the channel type.
