摘要 |
A method of generating a weight vector based on the maximum signal-to-interference-plus-noise output power ratio (SINR0) criteria without an eigenvector finding technique, is provided for use in a smart antenna system. The weight vector is applied after pseudo noise (PN) dispreading rather than in front of a receiver for channel estimation and data symbol demodulation. The method includes setting an initial weight vector w(0) and a convergence parameter or an initial eigenvalue. New post-PN processing vectors y(i) and new pre-PN processing vectors x(i) are received. The weight vector w(k) at a snapshot k is then updated and optimized.
