Abstract
Official abstract text for this publication.
A technique for decoding a signal in a communication network is provided. A method implementation of the technique comprises the steps of receiving a signal; identifying a position in the signal; initializing a Viterbi state metric; and decoding the encoded signal by means of a wrap-around Viterbi algorithm. The received signal comprises information, wherein the signal is encoded by a tail-biting convolutional code. The identified position relates to a known portion of the information. The initialized Viterbi state metric is consistent with the known portion of the information. The decoding uses the initial Viterbi state metric, wherein the decoding starts at a decoding step following the identified position.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of decoding a signal in a communication network, the method comprising: receiving a signal comprising information, wherein the signal is encoded by a tail-biting convolutional code; identifying a position in the signal related to a known portion of the information, wherein the known portion of the information includes a subset of a bit string of the information, wherein a length of the bit string is equal to or shorter than a memory of the c…
