An adaptive power amplifier and control subsytem for use in space-based software defined radio applications

Software defined radios have been a major paradigm shift in the communications area. Similarly autonomous/cognitive operations are a further enhancement to SDR operation. In progressing these technologies, particularly in applications requiring high-efficiency, adaptable transmit amplifiers and associated cognitive control-systems can help. This is particularly true for regions where immediate battery replacement is difficult at best, or, impossible at worst, i.e., space applications. If autonomous control can be performed in a prescribed manner, the overall operating efficiency of the radio should be increased with a subsequent increase in battery life and radio operating ability.
