Abstract
A double-dwell serial code acquisition system employing an adaptive threshold estimator is described and analyzed in frequency-selective Rayleigh fading channel. A general expression for the mean acquisition time is derived by considering the multiple H/sub 1/ cells and the 'returning' false alarm state. The problem of selecting the design parameters of the code acquisition system for CDMA forward link is also addressed based on the statistics of CDMA noncoherent QPSK demodulator output.
