摘要： The channelization of a WB OFDM channel may be determined by detecting a plurality of subchannels and generate a channelization vector indicating which of the subchannels are active and which of the subchannels are inactive. In response to the channelization vector, data-symbol processing may be performed on the active subchannels and may be refrained from being performed on the inactive subchannels. In some embodiments, a decoded bit stream may be generated from the combined contributions of the active channels. In some embodiments, the subchannels may be detected with a parallel set of matched filters. The matched filters may have a coefficient spectrum matched to a corresponding one of the subchannels.
摘要翻译： 可以通过检测多个子信道来确定WB OFDM信道的信道化，并且生成指示哪个子信道是活动的以及哪个子信道是非活动的信道化向量。 响应于信道化向量，可以对活动子信道执行数据符号处理，并且可以避免对非活动子信道执行。 在一些实施例中，解码比特流可以从活动信道的组合贡献产生。 在一些实施例中，可以用并行的一组匹配滤波器来检测子信道。 匹配滤波器可以具有与相应的一个子信道匹配的系数频谱。
