Ultra Wide Band (UWB) technology is a wireless carrier technology that does not use a sinusoidal carrier, but uses non-sinusoidal mode narrow pulses on the nanosecond scale to transmit data. In the ultra-wideband communication device in the prior art, since the transmitting power is limited by regulations, the receiving sensitivity of the ultra-wideband communication device needs to be improved as much as possible to expand the application distance of the ultra-wideband communication device. The method of setting dual receiving channels for ultra-wideband communication device to obtain combining gain is one of the methods of improving the receiving sensitivity.
Meanwhile, because the operating frequency of the ultra-wideband communication device is higher, the transmitted signal is easily influenced by external shielding, in the prior art, the quality of the received signal is generally judged through the RSSI (received signal strength Indication) of the received signal, so that the intelligent switching of the transmitting antenna is realized, and the quality of the transmitted signal is ensured.
In order to ensure the receiving sensitivity and the quality of the transmitted signal of the ultra wideband communication device at the same time, multiple transmitting and multiple receiving schemes are currently adopted in the industry.
