摘要： A method for field error checking begins by decoding a predetermined pattern of a field of a frame to produce a decoded pattern. The method continues by determining, for the decoded pattern, a path metric distance of a predetermined state of a plurality of states of the decoding. The method continues by comparing the path metric distance with an excepted path metric distance for the predetermined state. The method continues by indicating a field error when the path metric distance compares unfavorably with the excepted path metric distance.
摘要翻译：用于场错误检查的方法通过对帧的场的预定模式进行解码来产生解码图案。该方法通过针对解码图案确定解码的多个状态的预定状态的路径度量距离来继续。该方法通过将路径度量距离与预定状态的例外路径度量距离进行比较来继续。当路径度量距离与例外路径度量距离不利地比较时，该方法继续指示场错误。

摘要： A method and apparatus for decoding baseband OFDM signals include processing that begins by slicing each sub-carrier signal of the OFDM signal into a plurality of error terms. The particular number of error terms generated for each sub-carrier signal depends on the constellation size of the data being carried by each of the sub-carrier signals. The error terms for each sub-carrier signal corresponds to the nearest constellation point having a zero or one in the I or Q direction. The process continues by grouping individual error terms of the plurality of error terms for each sub-carrier signal to produce a plurality of error terms. The processing then continues by de-interleaving each of the plurality of error term groups to produce a corresponding plurality of de-interleaved error term groups. The processing then continues by interpreting the plurality of de-interleaved error term groups to produce a plurality of data values, each of the data values corresponds to data encoded within each of the sub-carrier signals.
摘要翻译：用于解码基带OFDM信号的方法和装置包括通过将OFDM信号的每个子载波信号分片成多个误差项开始的处理。为每个子载波信号产生的误差项的特定数量取决于每个副载波信号承载的数据的星座大小。每个子载波信号的误差项对应于在I或Q方向上具有零或一个的最近的星座点。该过程通过将每个子载波信号的多个误差项的各个误差项分组以产生多个误差项来继续。然后，该处理继续通过对多个误差项组中的每一个进行解交织以产生相应的多个解交错误差项组。然后，该处理继续解释多个解交错误差项组以产生多个数据值，每个数据值对应于在每个子载波信号内编码的数据。

摘要： A method for receiving high data rate wireless communication transmissions begins by receiving a plurality of radio frequency (RF) signals in accordance with a wireless communication standardized data rate on a plurality of RF channels. The method continues by converting each of the plurality of RF signals into a plurality of signals. The method continues by processing the plurality of signals at baseband or near baseband into media access control (MAC) data, wherein a number of the plurality of signals corresponds to an integer multiple. The method continues by processing the MAC data at a combination of wireless communication standardized data rates to produce recovered data.

摘要： A wireless communication device capable of receiving data using non-standard data includes a receiver section, a demodulation mapping module, a decoding module, and a rate determination module. The receiver section is operably coupled to convert a radio frequency signal into a digital signal. The demodulation mapping module is operably coupled to demodulate the digital signal to produce demodulated data. The decoding module is operably coupled to decode the demodulated data based on the coding rate to produce decoded data. The rate determination module is operably coupled to determine the coding rate from at least one of the digital signal and the demodulated data, wherein the coding rate is one of a plurality of standard coding rates or a non-standard coding rate that is selected for a given transmission.

摘要： A method and apparatus for establishing a non-standard data rate in a wireless communication system include processing that begins by establishing a standard specified data rate for a given transmission. The processing then continues by determining whether the data rate of the transmission can be adjusted from the standard specified data rate by a non-standard data rate adjustment. The processing then continues when the data rate can be adjusted, adjusting the data rate to a non-standard data rate for the given data transmission.
