Abstract
Low-Complexity Suppression of Adjacent Channel Interference in FDD Transceiver
Highlights
Wireless communication system usually achieves frequency-division duplex (FDD) operation by using duplexer
This paper proposed a suppression method to eliminate the adjacent channel interference (ACI) in FDD transceiver by using the transmitter leakage and baseband signal
The interference regeneration and cancellation were carried out in the digital baseband domain, which is preferable compared to radio frequency (RF) domain complexity
Summary
Wireless communication system usually achieves frequency-division duplex (FDD) operation by using duplexer In these FDD applications, it is still a big challenge to provide isolation simultaneously over both the TX and RX branches [1]. The sampling rate has been greatly reduced, the analog-to-digital converter (ADC) sampling bandwidth is three times the baseband signal bandwidth and still requires a certain amount of hardware resources. To tackle this issue, this paper proposed a memory polynomial (MP) method with duplexer fitting, which employed the transmitter leakage and baseband signal to estimate the system nonlinear parameters and regenerated and eliminated the interference.
