Adaptive digital receiver

摘要

The present invention provides a high-performance adaptive digital receiver with adaptive background control that optimizes the performance in rapidly changing signal environments and provides 3.6 GHz instantaneous bandwidth, SFDR>90 dB, SNR=66 dB, with dynamic digital channelization. The receiver takes advantage of several levels of adaptivity that conventional approaches do not offer. In addition to a dynamic digital channelizer that is adaptively tuned based on detected signals, the present invention employs a powerful software reconfigurable digitizer that is adaptively optimized for the current signal environment to control important receiver parameters such as bandwidth, dynamic range, resolution, and sensitivity.

1. A reconfigurable digitizer comprising:
an array of analog-to-digital converters, and digital signal processing logic, wherein the digital signal processing logic is reconfigurable based on input from a user or a detected signal environment, wherein reconfiguring the digital signal processing logic changes an operating parameter of the array of analog-to-digital converters, wherein the operating parameter is selected from the group consisting of: bandwidth, resolution, sensitivity, dynamic range, and any combination thereof.
