SYSTEMS AND METHODS FOR EQUALIZATION IN RADIO FREQUENCY SIGNAL PATHS |
摘要 |
The wireless communications device has a transmit signal path including a digital-to-analog converter and associated circuitry, a receive signal path including an analog-to-digital converter, and a magnitude detector sampling the transmit signal path and providing output to a signal controller. The signal controller is configured to determine amplitude distortion and determine phase distortion based upon information from the magnitude detector, and generate an equalization filter (e.g. during power-up of the wireless communication device), based upon the determined amplitude distortion and phase distortion, for pre-distortion of regular traffic output through the transmit signal path. The approach provides compensation for both amplitude and phase based upon the sampling of an output of a magnitude detector in Radio Frequency (RF) signal paths. |
