Embodiment 1
[0078] figure 1 Shown is a device and method for adaptively canceling received in-band interference in a wireless transceiver system, the device comprising:
[0079] RF transceiver channel and multi-channel coupling switch filter unit A, received signal cancellation unit B, received signal generation unit C, received signal frequency discrimination circuit D, downlink signal synchronization and frequency discrimination unit E, received interference signal cancellation unit F, data processing unit G;
[0080] The radio frequency transceiver path and multi-channel coupling switch filtering unit A are composed of a strip line or coaxial cable A3, a first coupler A2, a second coupler A4, a third coupler A5, a power feed circuit A6, a first radio frequency Switch A7, second radio frequency switch A9, third radio frequency switch A10, fourth radio frequency switch A12, fifth radio frequency switch A13, sixth radio frequency switch A15, first wave trap A8, second wave trap A11 and t...
Embodiment 2
[0138] An embodiment of the present application provides a method for adaptively canceling receiving in-band interference in a wireless transceiver system, wherein the method obtains the carrier configuration, frequency, and power information of the received signal according to the frequency discrimination of the received signal, and obtains the carrier configuration, frequency, and power information of the received signal according to the signal synchronization unit. The synchronization signal of the base station, and then the receiving signal generation unit generates a signal that is the same as the signal received by the receiving channel of the wireless transceiver. The following processes and methods include the frequency discrimination process of the received signal, the signal synchronization process, and the process of generating the received signal, such as Figure 7-9 shown;
[0139] First, conduct frequency discrimination on the received signal coupled from the main...
