Research on noise figure of a receiving system using adaptive interference cancellation

The use of adaptive interference cancellation (AIC) to solve the problem of the radiation interference of a transceiver system has attracted more and more attention. This paper analyzes the noise characteristics of a receiving system which uses an AIC technique for RF front-end filtering, and presents closed-form expressions for noise figure (NF). The comparison of differences between the noise performances before/after using the adaptive interference cancellation device (AICD) can help to comprehensively investigate the influence of the AIC technology on the receiving system.
