Performance Analysis of Pn Code Acquisition of a Smart Antenna System in a Ds/cdma Signal Environment

This paper presents a performance analysis of a novel searcher designed for array antenna in terms of average acquisition time as well as detection and false alarm probability. It has been shown that proposed searcher significantly reduces the acquisition time compared to the conventional searcher, which does not exploit the merit of array antenna structure. Due to the shortened acquisition time, which is provided by the phase diversity, the smart antenna system utilizing the phase diversity can enhance the demodulation performance, which consequently improves the system capacity, service area, and entire throughput.
