Abstract:
1. A circuit, comprising: a measurement circuit coupled to receive a first wideband code division multiple access signal, comprising at least one pilot, from a first antenna of a remote transmitter and coupled to receive a second wideband code division multiple access signal, comprising at least one pilot, from a second antenna of the remote transmitter, each of the first and second wideband code division multiple access signals being transmitted at a first time, the measurement circuit producing a first output signal corresponding to a magnitude of the first wideband code division multiple access signal and a second output signal corresponding to a magnitude of the second wideband code division multiple access signal; and a control circuit coupled to receive the output signal and a reference signal, the control circuit arranged to produce a first transmit power control signal and a second transmit power control signal at a second time in response to a comparison of the output signal and the reference signal, each of the first and second transmit power control signals set to control transmit power of respective said first and second antennas.
