Apparatus and method for detecting signals |
摘要 |
A circuit to improve the sensitivity of a receiver by more than 3 dB. According to the invention, conventional predetection integrators are replaced by a circuit to compute the correlation of the received signal with a delayed version of the received signal. The time delay is selected such that the noise in the signal and the delayed signal are statistically independent.
