| Abstract: | The key technique in Ultra-wideband(UWB) communication system, namely technique of UWB pulse signal detection and receiving, is discussed.An easy and novel method for high sensitiviy envelope detection is given according to the time domain characteristic of received signals. The realization and performance of the circuit is analysed. Meanwhile, experiment data and results are provided.Comparison with other methods indicates this circuit is an easy and useful noncorrelation detection method,and can get good performance when it cooperates with current correlation part in base band. |
