Patent ID: 8804881

Claim:
A receiving apparatus for detecting data streams in a communication system, the receiving apparatus comprising: a detecting apparatus comprising: a detector configured to detect, prior to initiating a decoding process, a number of data streams contained within a signal received on a single physical channel by comparing the received signal with plural predetermined sequences and identifying one or more of the plural predetermined sequences as being likely contained within the received signal, each data stream being associated with one of the plural predetermined sequences, at least one of the predetermined sequences being based on a training sequence assigned to a mobile station during registration of the mobile station in a network; and an indicator coupled to the detector and configured to provide an indication of the data streams likely contained in the received signal based on the identifying; and a decision device coupled to the detecting apparatus and configured to provide data defining a receiver configuration based on the indication, the receiver configuration being suitable for configuring a decoder to decode only the one or more data streams indicated as being likely contained in the received signal.
