摘要： In a tailbiting convolutional encoder the encoder (12) is initialized with a sequence of symbols corresponding to the final symbols of a sequence to be encoded, resulting in that the begin state and the final state of the encoder are the same. The problem of the convolutional code obtained by such a coder is that it requires substantial computational resources to decode it. In the simplified decoder according to the invention, the decoding process is extended by a plurality of trellis sections to a length N + nu . At the final trellis section, the state with the largest path metric is selected as the best state. This best state is used as starting point for a trace back operation to find an earlier state at N trellis section before the final trellis section. The earlier state found there is regarded as correct, having as consequence that the trellis should terminate also in said state. By performing a trace back from said state the source symbols can be found.

摘要： In a transmission system with a transmitter (4) coupled to a receiver (6) a main signal (SPEECH INPUT) encoded according to a coding property is transmitted together with an auxiliary signal (AUX). In order to transmit the auxiliary signal without needing additional space in the transmission frame, it is proposed to transmit the auxiliary signal by changing the coding property according to a predetermined sequence. This is done by means of the sequencer (13). In the receiver (6) the decoding of the predetermined sequence is performed by a decoder (31).
摘要翻译：在具有耦合到接收机（6）的发射机（4）的传输系统中，根据编码特性编码的主信号（SPEECH INPUT）与辅助信号（AUX）一起发送。为了在传输帧中不需要额外的空间来发送辅助信号，建议通过根据预定的顺序改变编码特性来发送辅助信号。这通过定序器（13）完成。在接收机（6）中，由解码器（31）执行预定序列的解码。

摘要： A series of data symbols is received. Unreliable units in the series of data symbols are detected on a per unit basis. A block of the data symbols that comprises a plurality of units is stored in a memory for de-interleaving. The information about unreliability has been found to have more redundancy than the data symbols. This used to reduce the amount of information stored for de-interleaving. Respective compressed reliability symbols are formed for successive parts of the series during reception of the series, using compressive coding of combinations of reliability information for respective ones of the units. The data symbols of the block are read from the memory in a de-interleaved order. The compressed reliability symbols are decompressed out of order, according to the de- interleaved order, in combination with said reading according to the de-interleaved order.
