Joint Radio-Frequency/Baseband Self-Interference Cancellation Methods |
摘要 |
System and method embodiments are provided for joint radio-frequency/baseband self-interference (SI) cancellation. In an embodiment, a method for reducing self-interference (SI) in a full duplex transmission system includes estimating a radio frequency (RF) SI signal according to a sampled received signal and a transmitted signal during a half-duplex operation; obtaining a corrected signal, wherein the corrected signal is a difference signal between an analog received signal and the estimated RF SI signal, and the corrected signal comprises an intended signal plus a residual SI signal; estimating the residual SI signal in a baseband during full duplex operation; and obtaining an intended signal, wherein the intended signal is a difference signal between the corrected signal in a digital domain and the estimated residual SI signal. |
