摘要： Various embodiments provide for systems and methods for increased linear output power of a transmitter. An exemplary wireless communications system for transmitting an input signal comprises a predistorter module, a GaN power amplifier, a coupler, and an antenna. The predistorter module is configured to detect existing distortion by comparing the input signal to a feedback signal and generate a correction signal. The predistorter may adaptively adjust its operation to minimize the existing distortion due to GaN power amplifier nonlinear characteristics. The result is that the GaN power amplifier may send a power signal of improved linearity to the antenna. The coupler is configured to sample the amplified signal from the GaN power amplifier to generate the feedback signal. The antenna is configured to transmit the amplified signal.

摘要： An adaptive broadband post-distortion receiver for wireless digital communications improves performance of a wireless digital communications system. The improved performance of the system includes improved linear AM-AM and AM-PM responses approaching saturation. Indeed, the proposed adaptive broadband post-distortion receiver has an effect on attributes such as bit error rate and transmitter power efficiency and, in turn, on modulation and bandwidth. The adaptive broadband post-distortion receiver is configured with an adaptively controlled IF post-distorter located at the IF stage of the receiver. The placement of the distortion canceling function in the IF section of the receiver lends itself to broadband applications. The post-distorter is configured to cancels the distortion produced by the transmitter and receiver as it is adaptively controlled using bit error rate calculations. The distortion canceling utilizes bit error rate information that is otherwise available in the receiver.
