Makalah ini mencadangkan pembatal gangguan jalur imej buta yang membolehkan penerima heterodina dengan hanya satu rantai penerima untuk menyahmodulasi isyarat dalam mana-mana jalur frekuensi. Dalam kertas ini, penerima sedemikian dipanggil "penerima heterodina berbilang mod/berbilang jalur." Jika penerima multimod/multiband dikehendaki menerima isyarat dengan frekuensi pembawa antara beberapa MHz hingga GHz, maka, penerima tersebut tidak dibenarkan mempunyai jalur sempit RF-BPF (Radio Frequency Band Pass Filter) di hujung hadapan RF. Walau bagaimanapun, walaupun penerima heterodina telah digunakan pada sistem wayarles kerana prestasinya yang tinggi, adalah diketahui bahawa tanpa penerima heterodina RF-BPF mengalami gangguan jalur imej yang teruk. Oleh itu, pembatalan gangguan jalur imej buta dicadangkan dalam kertas ini untuk mengurangkan gangguan jalur imej. Selain itu, algoritma baru berdasarkan kriteria CM (Constant Modulus) dicadangkan untuk melakukan pembatalan. Prestasi pembatal gangguan jalur imej buta dianalisis secara teori dan prestasi pembatalan yang dicadangkan disahkan oleh simulasi komputer. Akibatnya, ditunjukkan bahawa pembatal gangguan jalur imej buta mencapai prestasi unggul walaupun dengan kehadiran gangguan jalur imej yang kuat, contohnya, CIR=-40 dB. Ringkasnya, pembatalan yang dicadangkan membolehkan penerima dengan rantai penerima tunggal mencapai komunikasi berbilang mod/berbilang jalur dengan kualiti tinggi.

Abstract: This paper proposes a blind image-band interference canceller that enables heterodyne receivers with only a single receiver chain to demodulate signals in any frequency band. In this paper, such a receiver is called "multimode/multiband heterodyne receiver." If multimode/multiband receivers are desired to receive signals with carrier frequency ranging from several MHz to GHz, then, such receivers are not allowed to have a narrow band RF-BPF (Radio Frequency Band Pass Filter) at the RF front end. However, although heterodyne receivers have been applied to wireless systems due to their high performance, it is known that without an RF-BPF heterodyne receivers suffer from severe image-band interference. Therefore, a blind image-band interference canceller is proposed in this paper to mitigate the image-band interference. Moreover, a novel algorithm based on the CM (Constant Modulus) criterion is proposed to carry out the cancellation. Performance of the blind image-band interference canceller is theoretically analyzed and the performance of the proposed canceller is verified by computer simulation. As a result, it is shown that the blind image-band interference canceller achieves superior performance even in the presence of strong image-band interference, for example, CIR=-40 dB. In summary, the proposed canceller makes it possible for the receiver with the single receiver chain to achieve multimode/multiband communications with high quality.
