Scalable self-calibrating and configuring radio frequency head for a wireless communication system |
摘要 |
<p>A method, a system and a device for implementing a scalable, self-calibrating and configuring, radio frequency head in a wireless base station that performs phase calibration for coherent combining of a pair of transmitter outputs. Configurable Antenna Calibration CAC logic initiates phase calibration for coherent combining by selecting a first configuration and triggering the transmission of a reference signal by radio frequency RF transmitters using different sub-carriers. The CAC logic generates a vector of phase values by comparing the reference signal with the respective signals received by a calibration receiver. The CAC logic also generates calibration coefficients for coherent combining by normalizing the phase values. In addition, a passive combiner mechanism is employed to implement coherent combining. The CAC logic performs calibration of smart antennas by providing calibration coefficients via a second configuration which utilizes both a calibration transmitter and the calibration receiver.</p> |
