Abstract
A method and apparatus provide phase, frequency and gain characterization and mitigation in a synchronized code division multiple access (SCDMA) burst receiver via use of dedicated phase and frequency correction loops that implemented to deal with the unique characteristics of a SCDMA signal. The way coded and un-coded bits are interleaved within a given frame requires that all symbols related to that frame be captured in a dedicated storage medium such as a RAM prior to the beginning of the data processing. The method and apparatus substantially eliminate gain, phase, and frequency, among other impairments caused by the transmitter, channel and analog parts of the SCDMA burst receiver.
