ABSTRACT:
An iterative method and a device for decoding received signals transmitted in data frames via various channels. In order to be able to utilize the computing capacity of digital signal processors (DSPs) as efficiently as possible, it is proposed that, starting at a first channel, the quality of the decoded signal transmitted via the first channel is checked following every iteration and switchover takes place to at least one further channel if a specifiable switchover condition exists. The switchover condition may, for example, be a specifiable quality of the decoded signal transmitted via the channel under consideration. To determine the quality of the decoded signal a cyclic redundancy check (CRC), in particular, is proposed following every iteration.
