Sabe-se que um receptor multimodo heteródino implementado com um único receptor de RF (Radiofrequência) sofre interferência na banda de imagem devido ao desequilíbrio, ou seja, ao erro de fase e ao desequilíbrio de ganho do transformador RF Hilbert. O cancelador cego de interferência de banda de imagem com estimativa de desequilíbrio determinística que foi proposto mitiga a interferência de banda de imagem. Este desempenho do cancelador de interferência de banda de imagem é analisado teoricamente neste artigo. Como resultado, revela-se que a precisão da estimativa do desequilíbrio determinístico melhora ligeiramente à medida que o desequilíbrio se torna maior. Além disso, também é mostrado que a estimativa determinística atinge melhor desempenho à medida que aumenta o poder de interferência da banda de imagem. O desempenho é confirmado por simulação computacional.

Abstract: It is known that a heterodyne multimode receiver implemented with a single RF (Radio Frequency) receiver suffers from image-band interference due to imbalance, i.e. the phase error and the gain imbalance of the RF Hilbert transformer. The blind image band interference canceler with deterministic imbalance estimation that has been proposed mitigates the image-band interference. This performance of the image-band interference canceler is analyzed theoretically in this paper. As a result, it is revealed that estimation accuracy of the deterministic imbalance estimation is improved slightly as the imbalance becomes greater. In addition, it is also shown that the deterministic estimation achieves better performance as the power of image-band interference increases. The performance is confirmed by computer simulation.
