Abstract
Methods and apparatus for phased-based pre-carrier signal detection in a communication system are described. In embodiments, inphase and quadrature (IQ) data is generated from a received signal. A current phase delta value is determined from the IQ data and combined with existing phase delta value, such as an averaged phase delta value, which is compared with a threshold value to determine if a pre-carrier signal in the received signal has ended.
