ABSTRACT:
A novel and improved method and apparatus for coherently processing a CDMA signal without the use of pilot or other synchronization information is described. By utilizing a coherent receive processing system, a reverse link signal can be properly processed when received at a lower power level than that associated with noncoherent only processing. This reduces the transmit power necessary for successful communication, and this reduction in necessary transmit power reduces the degree to which a set of subscriber units communicating with the same base station interfere with one another. In turn, this increases the overall system capacity of a CDMA wireless telecommunication system incorporating the invention.
