System and method for radio signal reconstruction using signal processor

摘要

A waveform reconstruction circuit receives an rf signal from an antenna, digitizes it, and then generates an undistorted reconstructed waveform. The reconstructed waveform can then be conventionally mixed and demodulated to extract useful signal information with enhanced receiver fidelity and sensitivity.

1. An apparatus comprising:
a converter receiving as input a sinusoidial signal that has not been downconverted in the analog domain, the converter outputting a digitized signal representing the rf signal; and a hardware module electrically connected to the converter, the module being configured with software to extract baseband information from the digitized signal, wherein the module corrects at least one non-sinusoidal distorted portion of the signal.
