Patent ID: 8311154

Claim:
A method of receiving data in a wireless communication system, comprising: obtaining samples for a burst comprising at least one data field and a common midamble; deriving multiple channel estimates for multiple orthogonal codes comprising multiple channel impulse response estimates based on samples for the common midamble and samples for the at least one data field, comprising: deriving a first channel impulse response estimate based on the samples for the common midamble, estimating a traffic-to-pilot ratio (T2P) for each of the multiple orthogonal codes based on the samples for the at least one data field and the samples for the common midamble, and deriving a second channel impulse response estimate for each of the multiple orthogonal codes based on the first channel impulse response estimate and the T2P for the orthogonal code; and performing joint detection, for the multiple orthogonal codes, on the samples for the at least one data field based on the multiple channel estimates.
