Abstract :
The correlation receiver detects a signal by comparing the input waveform, containing noise and interference, with a reference waveform. This principle can now be applied up to microwave frequencies and we have detected a signal/noise ratio of ¿53dB in an input bandwidth of 1GHz. This is far from the theoretical performance and improvement in components can reduce the limit much further.
