Disclosed are a signal receiving method and apparatus, and a communication device. The method comprises: a receiving antenna receiving a signal and transmitting same to a frequency selection filter; the frequency selection filter outputting signals at different frequency bands to corresponding transmission branches; after processing the signals by utilizing an adjustable gain amplifier and a noise suppression filter which are sequentially connected, the transmission branches transmitting same to a combiner; after processing an input signal of each transmission branch, the combiner outputting same to a radio frequency sampler; and after processing the signal output by the combiner, the radio frequency sampler outputting same to a signal processing apparatus in a device. |
