Embodiment Construction
[0016] The present invention will be described in further detail below in combination with specific embodiments and with reference to the accompanying drawings.
[0017] Such as Figure 4 As shown, it is a structural diagram of a UWB communication system based on CS theory in this specific embodiment, including a transmitting end 41 , a UWB channel 42 and a receiving end 43 .
[0018] The transmitting end 41 includes a random precoding module 4101 and a pulse generating module 4102 . The data packet to be sent in the pulse ultra-wideband communication system is represented as a digital signal X, and the digital signal X is randomly transformed into a transformation vector Z by the random precoding module 4101, and then superimposed on the UWB pulse generated by the pulse generation module 4102 to obtain a transmission signal u(t) , thereby emitting.
[0019] UWB channel 42 receives the transmit signal output by the pulse generation module 4102 u(t) , the output receiver s...
