Abstract
Provided is a signal cancellation method for a wireless communication system, including: splitting a transmitted signal to obtain a main channel signal transmitted on a main channel and an auxiliary channel signal transmitted on an auxiliary channel; performing digital domain channel characteristic matching processing on the main channel signal and the auxiliary channel signal respectively to obtain a main channel characteristic matched signal and an auxiliary channel characteristic matched signal; and combining the main channel characteristic matched signal and the auxiliary channel characteristic matched signal which are coupled to a receiving channel in order for signal cancellation. A signal cancellation device for a wireless communication system is also provided. Through the technical solution of the disclosure, the signal cancellation problem of a bandwidth can be solved better.
