Comparison of Intelligent Code Acquisition for Sectorized Multi-Antenna CDMA in Downlink Mode

Authors: A. Scherb, V. Kühn, K.-D. Kammeyer
Abstract: This paper presents two different code acquisition schemes for sectorized multi-antenna CDMA systems in downlink mode. The so called ”separated code optimization” (SCO) decomposes a two dimensional spreading code into its time and space component and treats each part separately. The SCO maximizes the signal to interference and noise ratio at each receiver. In contrast, the ”joint code optimization” (JCO) does not distunguish between time and space component and acquires the code simultaneously. Both methods are evaluated by Monte Carlo simulations and their performance are compared.
