Power inversion adaptive array antenna for high power interference suppression in DS-CDMA system
Kazunari Kihira, Isamu Chiba · 2002
We propose an adaptive array antenna for high power interference suppression in DS-CDMA (direct sequence code division multiple access) system. In the proposed adaptive array, the interference cancellation is performed by a two-element array antenna using an auxiliary antenna before despreading. It is not necessary to derive the weights for each channel thus it can decrease the consumption power of the system. We describe the results of numerical calculation using a fundamental model.
