Abstract
A wireless transceiver () that produces soft decisions for received, block error correction encoded codewords and a confidence indicator signifying a likelihood of errors in the detected data. The wireless transceiver () processes block encrypted signals, such as feedback channel messages in a WiMax uplink. Upon receiving a signal, a soft decision is determined for received block encoded codewords. A difference is calculated between a soft decision metric for a most likely detected codeword and a soft decision metric for a next most likely detected codeword. This difference is normalized based upon the total decoder input power received over the received signal (). The normalized difference is then scaled by a channel dependent factor and is time filtered. The normalized and time filtered confidence indicator output () is able to be provided to a wireless network controller to assess the usability of the received data.
