SMART ANTENNA RECEIVING APPARATUS AND METHOD USING PILOT SIGNAL IN CDMA MOBILE COMMUNICATION SYSTEM

摘要

The present invention multiplies each wireless signal received through a plurality of antennas by adaptive weights and adds the sum totals to output the array output signal, multiplies the array output signal by a pseudo noise code, filters the despread signal, and then adjusts the amplitude. By calculating the difference between the reference signal generated by respreading by multiplying the amplitude-adjusted signal by the pseudo noise code and the array output signal, and generating an error signal, an optimal adaptive weighting value through the error signal and the wireless signal. A receiver and method using a pilot signal are implemented in a CDA mobile communication system that generates an adaptive weight convergence.
