1. A method for blind detection of a transport format of an interferring signal, the method comprising steps of: receiving a composite signal comprising one or more interfering signals, including the interfering signal, and at least one desired signal; filtering a set of transport format hypotheses to identify a reduced set of transport format hypotheses using one or more filtering schemes; from the reduced set of transport format hypotheses, detecting a transport format associated with the interfering signal, the transport format comprising a modulation and a spreading factor for the interfering signal; the transport format further comprises a number of channelization codes for the interfering signal; and the step of filtering comprises the step of applying the one or more filtering schemes to filter transport format hypotheses based on a system configuration that establishes relationships between spreading factors and number of channelization codes.
