Untuk meningkatkan prestasi penjejakan, gangguan dan pengurangan berbilang laluan daripada yang mungkin dengan isyarat sedia ada, isyarat Sistem Satelit Navigasi Global (GNSS) baharu diperlukan yang boleh menawarkan darjah kebebasan tambahan untuk membentuk bentuk gelombang dan spektrum nadinya. Dalam makalah ini, satu skim modulasi baharu yang dipanggil Quinary Offset Carrier modulation (QOC) dicadangkan sebagai reka bentuk isyarat GNSS baharu. Bentuk gelombang nadi modulasi QOC dibahagikan kepada dua jenis: bentuk gelombang cembung dan cekung. Modulasi QOC boleh dibina dengan mudah dengan memilih parameter modulasi yang berbeza. Ciri-ciri spektrum dan autokorelasi modulasi QOC disiasat dan dibincangkan. Simulasi dan analisis menunjukkan bahawa modulasi QOC boleh mencapai prestasi yang serupa dengan modulasi BOC tradisional dari segi penjejakan kod, anti-multipath dan keserasian. Modulasi QOC boleh menyediakan pilihan baharu untuk reka bentuk isyarat navigasi satelit.

Abstract: In order to improve tracking, interference and multipath mitigation performance from that possible with existing signals, a new Global Navigation Satellite System (GNSS) signal is needed that can offer additional degrees of freedom for shaping its pulse waveform and spectrum. In this paper, a new modulation scheme called Quinary Offset Carrier modulation (QOC) is proposed as a new GNSS signal design. The pulse waveforms of QOC modulation are divided into two types: convex and concave waveforms. QOC modulations can be easily constructed by selecting different modulation parameters. The spectra and autocorrelation characteristics of QOC modulations are investigated and discussed. Simulations and analyses show that QOC modulation can achieve similar performance to traditional BOC modulation in terms of code tracking, anti-multipath, and compatibility. QOC modulation can provide a new option for satellite navigation signal design.
