Abstract
A waveform reconstruction system and method for using the same are disclosed. The system includes an RF down-converter that receives a signal and outputs a down-converted signal. A demodulator demodulates the down-converted signal to generate a recovered digital data stream. A pattern detector detects a predetermined pattern in the recovered digital data stream. A delay generator delays the down-converted signal and outputs a delayed copy thereof. A signal processing circuit combines the delayed copy with previously received delayed copies of the down-converted signal to reconstruct an averaged waveform from the plurality of delayed copies having the predetermined pattern.
