Abstract:
1. A multi-carrier receiving device, comprising an antenna, a splitting module, a combiner, an analog-to-digital converter, M analog extraction modules, and N digital extraction modules, wherein M is an integer larger than 2, and N is an integer larger than or equal to M; the antenna is configured to receive a multi-carrier signal, and the multi-carrier signal comprises N single-carrier signals; the splitting module is configured to split the multi-carrier signal into a plurality of band signals in accordance with different bands, wherein any one of the band signals comprises one single-carrier signal, or a plurality of discrete single-carrier signals, or a plurality of continuous single-carrier signals, and the number of the plurality of band signals is less than or equal to M; the M analog extraction modules are configured to perform frequency conversion and analog filtering on the plurality of band signals to obtain L intermediate signals, wherein one band signal corresponds to at least one analog extraction module, bands of the L intermediate signals are different and continuous, and M≦L≦N; the combiner is configured to combine the L intermediate signals into one analog signal in accordance with a manner of adding bandwidth together; the analog-to-digital converter is configured to perform analog-to-digital conversion on the analog signal obtained after the combination to obtain one digital signal; and the N digital extraction modules are configured to extract N single-carrier digital signals which are in one-to-one correspondence with the N single-carrier signals comprised in the multi-carrier signal from the digital signal.
