Abstract:
1. A method for determining whether an encoded message in a shared channel is not intended for a communications device, the method comprising: (a) decoding the message to recover a multi-bit codeword; (b) determining whether the codeword is valid or invalid, wherein, if the codeword is determined to be invalid, then the encoded message is not intended for the communications device; and (c) if the codeword is determined to be valid, then performing one or more other steps of the method to determine whether the encoded message in the shared channel is not intended for the communications device, wherein: steps (a) and (b) are performed in parallel for a plurality of shared channels; the one or more other steps comprise: the at least one single-channel step comprises: the at least one multi-channel step comprises: the re-encoded correlation value is determined using the equation wherein: S the correlation value is compared to a threshold by comparing Corr to Ene.40.Th, wherein Th is a correlation threshold, and
