ABSTRACT:
Provided is a method, apparatus and computer program product for detecting a transport format of a multiplexed transport channel used for transferring binary data. A path metric value is determined, which estimates likelihood for a hypothetical trellis path to end at a predetermined state, for every state of a trellis stage of a possible end bit position of a data block of the transport channel. Then, for each possible end bit position a number of path metric values which indicate higher likelihood for the hypothetical trellis path to end at said predetermined state than an initial state is calculated, and the best end bit positions which lead to highest values of the calculated number are selected and error checking is performed for the selected best end bit positions to detect the transport format. The proposed selection of best end bit positions leads to a reduced number of decoding operations.
