Comparison of two Strategies for Serial Acquisition of CDMA

Spread spectrum code division multiple access (CDMA) is rapidly becoming the most commonly used pseudorandom modulation technique for mobile communication systems wideband CDMA-WCDMA, CDMA 2000...etc. The most important problem with the communication is the reliable synchronization of transmitter and receiver. This is typically achieved in two phases: acquisition (coarse synchronization) and tracking (fine synchronization) from the work of C.A. Putnam and S.S. Rappaport (1983). In this paper we analysis two strategies and analytically obtained: the lock probability, the mean dwell time, the mean acquisition time and the mean hold time, for both strategies
