CMA-based Code Acquisition Scheme for DS-CDMA Systems

Cheung, P; Rapajic, P


In direct-sequence code-division multiple access, a code synchronization must take place before the multiuser detector. As the initial synchronization stage, code acquisition scheme is used to estimate the relative timing phase for the desired transmission within one chip interval. In this paper, a blind code acquisition scheme using adaptive linear filtering based on a linearly constrained constant modulus algorithm (CMA) is proposed. The uncertainty of a desired user's delay is initially...[Show more]
