摘要：
Some search strategies for code acquisition in the delay and angular domains in radio environments with colored spatial distribution of interference are studied in this paper. The basic strategies comprise the Fix Angle Sweep Delay and Fix Delay Sweep Angle approaches to search the uncertainty region. A simple algorithm combining the Fix Angle Sweep Delay scheme with an ordered search according to the interference level associated with each angular cell is proposed Comparisons in different scenarios show that the proposed approach greatly improves acquisition performance.
