Abstract
Methods and apparatus are provided for blind transport format detection using Discontinuous Transmission (DTX) detection. According to one aspect of the invention, the transport format that was used to transmit information is determined by identifying a transition between a Discontinuous Transmission segment and a data segment included in the transmitted information; and determining the transport format based on a location of the transition of the Discontinuous Transmission segment. A cyclic redundancy check can optionally be performed for a plurality of possible transport formats, and then the step of identifying a transition can be limited to those transport formats having a valid cyclic redundancy check.
