Dalam makalah ini, kami membentangkan kaedah untuk menganalisis prestasi keadaan mantap penapis takuk IIR adaptif kompleks pekali yang berguna untuk penolakan pelbagai gangguan jalur sempit daripada isyarat jalur lebar dalam penyebaran kekunci anjakan fasa kuadratur (QPSK). sistem komunikasi spektrum. Penapis takuk penyesuaian berdasarkan algoritma kecerunan yang dipermudahkan dipertimbangkan. Ungkapan analitik telah dibangunkan untuk min bersyarat dan varians keluaran penapis takuk. Faktor penambahbaikan nisbah isyarat-ke-bunyi juga diperoleh daripada mana kesahihan penggunaan penapis takuk boleh disimpulkan. Akhirnya, keputusan simulasi komputer ditunjukkan yang mengesahkan ramalan teori.

Abstract: In this paper, we present a method to analyze the steady-state performance of a complex coefficient adaptive IIR notch filter which is useful for the rejection of multiple narrow-band interferences from broad-band signals in quadrature phase shift keying (QPSK) spread-spectrum communication systems. The adaptive notch filter based on the simplified gradient algorithm is considered. Analytical expressions have been developed for the conditional mean and variance of notch filter output. The signal-to-noise ratio improvement factor is also obtained from which the validity of the use of the notch filter can be concluded. Finally, the results of computer simulations are shown which confirm the theoretical predictions.
