Wireless communication signal frequency spectrum moving method and system

The invention relates to the technical field of wireless communication, in particular to a wireless communication signal frequency spectrum moving method and system. The moving method comprises the following steps: 1) carrying out baseband signal processing and ADC analog-to-digital conversion on a baseband signal of an input FDD/TDD signal, and moving a frequency point to a specified central frequency point; 2) enabling an FPGA chip to sequentially filter and copy N parts of the obtained central frequency point signals, and respectively reduces or amplifies the power of the N parts of signals; and 3) performing DAC digital-to-analog conversion on the reduced or amplified N signals, and outputting the signals to a plurality of different frequency points. According to the invention, movement of FDD and TDD wireless communication signals on different frequency spectrum can be rapidly and flexibly realized, simultaneous movement of one path of FDD and TDD signals on a plurality of different frequency spectrum ca
