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 distinguish between time and space component and acquires the code simultaneously. Both methods are evaluated by Monte Carlo simulations and their performance are compared.
