| Abstract: | PN (Pseudo-Noise) code acquisition is the most challenging task in a Direct Sequence Spread Code Division Multiplex Access (DS-CDMA) for celluar mobile communication systems. In this paper, based on energy windows acquisition of the time and frequency uncertainty of the received signal is investigated. Based on energy windows acquisition exploits the inherent multi-path diversity of the channel, and has better performance than single-path one when working in multi-path fading environment. |
