JOINT DETECTOR/DECODER DEVICES AND JOINT DETECTION/DECODING METHODS

摘要

There is provided a joint detector/decoder device including an input circuit configured to receive an input signal including a bit sequence, a soft information determining circuit configured to determine soft information with respect to the received bit sequence, a survivor splitting circuit configured to produce a plurality of survivors of a next instance based on at least one survivor of a previous instance and based on the received bit sequence, a threshold parameter controlling circuit configured to control a threshold parameter based on the soft information determined, and a survivor discarding circuit configured to discard one or more survivors based on a set of predetermined criteria. In particular, the set of predetermined criteria includes a first predetermined criterion based on the threshold parameter. Furthermore, each survivor has an associated bit sequence. There is also provided a corresponding joint detection/decoding method.
