摘要： Disclosed is a system and method for compensating for the effects of aging and temperature on the performance of transistors in an RF transmitter. The system and method use a temperature-based polynomial and a feedback control loop to correlate the drain current of each transistor with the desired performance characteristics of each transistor. The present invention measures drain current and temperature of the transistor; compares the measured drain current with the desired drain current, which corresponds to the desired performance characteristics; computes a transistor bias voltage based on the temperature and a control parameter, wherein the control parameter is adjustable based on the measured drain current; and applies the bias voltage to the transistor. The process may be repeated, with the control parameter adjusted with each iteration, until the desired drain current is reached.

摘要： A method to receive channels in an undersampled broadband receiver is provided. The method includes converting received radio frequency signals to downshifted-sampled-digital signals at an analog-to-digital converter in a sampling system, outputting the downshifted-sampled-digital signals to a digital system for digital processing, and determining if the unique identifying code associated with a desired channel is detectable. Each channel in the radio frequency signal has an assigned unique identifying code. When the unique identifying code is detectable, the method includes detecting the unique identifying code associated with the desired channel. When the unique identifying code is undetectable, the method includes outputting control signals from the digital system to tune an adjustable sample clock in the sampling system and tuning the adjustable sample clock based on the output control signals.

摘要： Systems and methods for reducing interference in an enhanced radio receiver from a transmitter when both are located in the same aircraft are provided. The enhanced radio receiver detects and attenuates a signal from the transmitter, without attenuation or interference with other desired signals. An enhanced radio transmitter may inform the enhanced radio receiver of the frequency of transmission via a data communication path such that the enhanced radio receiver attenuates the transmitted frequency for the duration of transmission.

摘要： Systems and methods are described for increasing the effective dynamic range of a digital data stream in a software-defined radio receiver. In one system the sample rate of an analog to digital (“A/D”) conversion process is adjusted dynamically to shift harmonic signal interference induced by the A/D conversion process to outside the channels of interest. In another system the sample rate of an A/D conversion process is constant and the frequency of a dynamically controlled local oscillator in a frequency translator is adjusted dynamically to shift harmonic signal interference induced by the A/D conversion process to outside the channels of interest.
