ABSTRACT:
For each of one or more received trellises, a convolutional decoder (808) determines a path metric (812) and a signal strength estimator (809) determines a signal strength estimate (813). A signal quality estimator (810) processes the path metrics and signal strength estimates for each of the received trellises and produces a received signal quality estimate (814), the received signal quality estimate being indicative of a signal-to-interference-plus-noise ratio, a bit error rate, or a block error rate. This approach is well-suited for use with schemes having high-order symbol constellations. When incorporated into an RF transceiver 700, the received signal quality estimate can be used in the selection of an encoding scheme best adapted to ongoing RF channel conditions.
