METHOD AND SYSTEM FOR IMPLEMENTING SMART ANTENNAS AND DIVERSITY TECHNIQUES

摘要

PROBLEM TO BE SOLVED: To solve a problem that it is extremely preferable to provide a capability of selecting an antenna receiving (or transmitting) a best quality signal.;SOLUTION: The present invention relates to a method and apparatus for converting a common radio frequency (RF) chain from multiple antennas to baseband. Antenna selection is performed while having greater flexibility and applicability to both uplink and downlink wherein priority is given to the antenna receiving a better quality signal. Measurements are taken during each time slot to determine the weighting to be given to the antenna with the better quality signal. Techniques and apparatus are provided to take measurements over a range of intervals from time slots to single symbols. In order to select the best signal, the techniques described herein may be used individual and, in some cases, are combined to receive additional benefits in efficiency.;COPYRIGHT: (C)2007,JPO&INPIT
