Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings.
[0021] A kind of OPPM-UWB wireless communication method based on time reversal technology, comprises the following steps:
[0022] Step 1: The receiving end first determines the modulated pulse x(t) of the corresponding pulse width according to the transmission rate of OPPM-UWB wireless communication and sends it out. After the modulated pulse x(t) is transmitted through the multipath wireless channel, set the received The signal is y(t), and then the sending end performs time inversion operation on the received signal y(t) to obtain the inversion signal s(t)=y(T-t), where T is the length of the received signal.
[0023] Step 2: The sending end uses the inversion signal s(t) obtained in Step 1 as a modulated pulse for suppressing multipath interference to perform OPPM modulation on the information to be sent and send it.
[0024] Step 3: The receiving end receives the...
