METHOD AND SYSTEM FOR USE OF QUADRATURE HYBRIDS FOR CLOSED AND OPEN LOOP BEAM FORMING TRANSMIT DIVERSITY

摘要

The present implementation is directed to a system and method of mobile transmit diversity and, more particularly, to a device which can operate in any of several modes, including a transmit diversity mode whereby two or more antennae transmit signals to at least one base station with relative phase difference, or in a non-diversity mode whereby one antenna is turned off and the other transmits at full or requisite power.
