Abstract

The techniques of intelligent interference cancellation are used for achieving the improvement of deterioration, which is arisen to the interoperable terminal(GSM and DVB-H). In this paper, we propose a novel system that improve the DVB-H received performance by using the method of an adaptive interference canceller for GSM900 and DVB-H terminal. The interference for the collocated GSM900 and DVB-H receiver is cancelled by using the adaptive canceller with the low-noise ADC(Analog to Digital Converter) in the RF stage.

GSM 단말기에서 GSM 통신모듈과 DVB-H 방송 수신기가 복합화 되었을 경우, GSM 신호의 간섭으로 인해 DVB-H 수신 성능이 감소된다. 본 논문에서는 적응형 간섭 잡음제거 기법으로 GSM 간섭 신호성분을 제거함으로써 DVB-H 수신 성능을 개선하는 시스템을 제안한다. Low-noise ADC를 포함한 적응형 필터를 설계함으로써 RF단에서 간섭 잡음신호를 제거할 수 있다.
