摘要：
In this paper, presents interference suppression using a Space Time Block Coding-Subband Adaptive Array (STBC-SBAA) for uplink W-CDMA system over frequency selective fading channel is presented. The proposed scheme utilizes W-CDMA system with STBC and a receive array antenna with SBAA processing at the receiver. The received signal is converted into the frequency domain before despreading and adaptive processing is performed for each subband. A novel SBAA construction is introduced to process W-CDMA signals based on STBC. To improve the performance of the proposed scheme, the evaluation is performed over STBC-SBAA using spreading codes. Simulation results demonstrate an improved performance of the proposed system for single and multiuser environments compared to competing related techniques.
