Dalam kajian ini, skim julat yang cekap dari segi pengiraan yang mengeksploitasi ralat min kuasa dua minimum (MMSE) dan teknik pensel matriks (MP) dicadangkan untuk sistem spektrum hamparan kicauan (CSS) IEEE 802.15.4a. Berdasarkan ciri-ciri isyarat CSS, metodologi praktikal untuk proses MMSE dirangka dan nilai parameter yang sesuai, iaitu jalur lebar cutoff, bilangan sampel dan tempoh pensampelan dalam domain frekuensi, disiasat dan ditentukan secara numerik untuk meningkatkan prestasi. Prestasi skim yang dicadangkan dianalisis dari segi kerumitan pengiraan dan ralat anggaran julat. Keputusan simulasi menunjukkan bahawa skim yang dicadangkan berprestasi serta skema konvensional pada kos pengiraan yang sangat berkurangan.

Abstract: In this study, a computationally efficient ranging scheme exploiting a minimum mean square error (MMSE) and a matrix-pencil (MP) technique is proposed for the IEEE 802.15.4a chirp spread spectrum (CSS) system. Based on the characteristics of the CSS signal, a practical methodology for the MMSE process is devised and the appropriate values of parameters, which are cutoff bandwidth, number of samples and sampling duration in frequency domain, are investigated and numerically determined to enhance the performance. The performance of proposed scheme is analyzed in terms of the computational complexity and the ranging estimation errors. Simulation results demonstrate that the proposed scheme performs as well as the conventional scheme at remarkably reduced computational costs.
