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： According to various embodiments, systems and methods are provided for improving signal quality and signal reliability over wireless communication using polarization diversity. Some embodiments use polarization diversity on a wireless channel to address and compensate for fading conditions such as non-frequency selective fading (also referred to as power fading, attenuation fading, and flat fading) and frequency selective fading (also referred to as multipath fading and dispersive fading). For example, some embodiments utilize a horizontal signal and a vertical signal on the same wireless channel when wirelessly communicating data between a transmitter and a receiver to address a fading condition.
