Pengoptimuman penyesuaian jalur lebar takuk bagi penapis takuk tindak balas impuls tak terhingga (IIR) adaptif berasaskan kekisi dibentangkan dalam kertas kerja ini. Penapis digunakan untuk meningkatkan prestasi sistem komunikasi spektrum penyebaran jujukan terus (DSSS) perduaan anjakan anjakan (BPSK) dengan menekan gangguan jalur sempit pada penerima. Algoritma kuasa dua terkecil (LMS) yang digunakan untuk menyesuaikan pekali lebar jalur takuk kepada nilai optimumnya yang sepadan dengan faktor peningkatan nisbah isyarat kepada hingar (SNR) maksimum diperolehi. Peningkatan kadar ralat bit (BER) yang diperolehi oleh sistem komunikasi DSSS menggunakan penapis dengan lebar jalur takuk yang dioptimumkan juga ditunjukkan. Keputusan simulasi komputer dibandingkan dengan yang diperoleh secara analitik untuk menunjukkan kesahihan ramalan teori bagi pelbagai parameter isyarat yang diterima.

Abstract: Adaptive optimization of the notch bandwidth of a lattice-based adaptive infinite impulse response (IIR) notch filter is presented in this paper. The filter is used to improve the performance of a direct sequence spread spectrum (DSSS) binary phase shift keying (BPSK) communication system by suppressing a narrow-band interference at the receiver. A least mean square (LMS) algorithm used to adapt the notch bandwidth coefficient to its optimum value which corresponds to the maximum signal to noise ratio (SNR) improvement factor is derived. Bit error rate (BER) improvement gained by the DSSS communication system using the filter with the optimized notch bandwidth is also shown. Computer simulation results are compared with those obtained analytically to demonstrate the validity of theoretical predictions for various received signal parameters.
