|1. (WO2018098666) METHOD AND DEVICE FOR RECEIVING SIGNALS|
|Applicants:||HUAWEI TECHNOLOGIES CO., LTD.
|Title:||METHOD AND DEVICE FOR RECEIVING SIGNALS|
Disclosed in the present application are a method and a device for receiving signals, which relate to the field of communication technology. The present invention can eliminate the interference portion introduced by inter-symbol interference (ISI) contained in signals without amplifying white noise, thereby improving the transmission performance of signals. The method comprises: receiving a first signal, the first signal containing an interference portion introduced by ISI; performing linear equalization, demodulation and decoding of the first signal to obtain a second signal; estimating the interference portion, according to the second signal, to obtain a first interference estimation signal; subtracting the first interference estimation signal from the first signal to obtain a third signal; demodulating and decoding the third signal to obtain a first output signal.
