摘要： A forward error correction and differentially encoded signal obtained via a communication channel is supplied to a soft-input soft-output (SISO) differential decoder that is bi-directionally coupled to a SISO forward error correction decoder. Over a first portion of a plurality of decoding iterations of the differentially encoded signal, the SISO differential decoder and the SISO forward error correction decoder are operated in a turbo decoding mode in which decoded messages generated by the SISO differential decoder are supplied to the SISO forward error correction decoder and forward error correction messages are supplied to the differential decoder. Over a second portion of the plurality of decoding iterations of the differentially encoded signal, the SISO forward error correction decoder is operated in a non-turbo decoding mode without any messages passing to and from the SISO differential decoder. Decoder output is obtained from the SISO forward error correction decoder.

摘要翻译： 经由通信信道获得的前向纠错和差分编码信号被提供给双向耦合到SISO前向纠错解码器的软输入软输出（SISO）差分解码器。 在差分编码信号的多个解码迭代的第一部分中，SISO差分解码器和SISO前向纠错解码器以turbo解码模式操作，其中由SISO差分解码器产生的解码信息被提供给SISO前向 纠错解码器和前向纠错消息被提供给差分解码器。 在差分编码信号的多个解码迭代的第二部分上，SISO前向纠错解码器以非turbo解码模式操作，而没有任何消息传送到SISO差分解码器。 解码器输出从SISO前向纠错解码器获得。

摘要： A method for encoding bits according to a convolutional code. Bits to be encoded with the convolutional code are obtained for transmission over a communication channel. The bits are encoded according to the convolutional code with an encoder having an M-bit memory and a plurality of logic gates so as to separate trellis segments of the convolutional code into trellis sub-segments having a reduced number of branches per state than that of the trellis segments.
