  • Techniques for linearizing phase independently of amplitude in a communications system
    Patent number: 9548822
    Abstract: The present disclosure, for example, relates to one or more techniques for linearizing a signal in a communications system. An input signal may be obtained at a beginning of a signal path of a radio frequency (RF) communication device. The RF communication device may estimate subsequent distortion of the input signal due to the signal path. The estimated distortion may include estimated phase distortion and estimated amplitude distortion of the input signal. The RF communication device may adjust phase and amplitude within the signal path to compensate for the estimated phase distortion and the estimated amplitude distortion to produce an adjusted signal. The phase within the signal path of the input signal may be adjusted separately from the amplitude within the signal path of the input signal. The RF communication device may generate a linearized signal at an end of the signal path based at least in part on the adjusted signal.
