摘要
A system for facilitating the detection and successful decoding of a quick paging channel adapted for use with a wireless communications system supporting a primary paging channel and a quick paging channel. The system includes a first mechanism for detecting a pilot signal associated with the quick paging channel based on a received signal and includes a coherent integrator of a first length and a noncoherent integrator of a second length. The second mechanism determines receiver operating characteristics of the system based on the pilot signal and a quick paging channel signal associated with the quick paging channel. The third mechanism optimizes the first length and the second length based on the receiver operating characteristics. In a specific embodiment, the first mechanism includes a CDMA receive chain for receiving the received signal and providing a digital received signal in response thereto to a sample Random Access Memory (RAM). The sample RAM includes a mechanism for sampling the digital received signal at predetermined time slots and providing a sampled received signal in response thereto. An interpolator adjusts the rate of the sampled received signal and provides a rate-adjusted signal in response thereto. The first mechanism includes a searcher that includes the first coherent integrator, a second coherent integrator, and the noncoherent integrator. A complex despreader correlates the rate-adjusted received signal with a pseudo noise candidate code and providing a correlation result in response thereto.
