摘要: 本文提出了一種用于CDMA系統(tǒng)的新型智能天線。這種智能天線采用近似等旁瓣方向圖,加權矢量無需預先測量、校正,可由累加、平均算法獲得,具有良好的工程實現(xiàn)性。本文提出的智能天線與自適應智能天線具有相似的擴容能力,但它無需迭代、響應速度快、魯棒性也更好。Abstract: A new smart antenna for CDMA system was proposed in the paper. The beam pattern with approximately equal side lobe is adopted. The weighting vectors are got not by measuring or rectifying in advance, they can be got by average method, and can be realized easily in engineering. The enhanced capability of this antenna is approximately equal to adaptive antenna, but need not iterative procedure, has fast response and good robustness.
