Abstract
Recently, interest in a new RNSS (Radio Navigation Satellite Service) for Korea [1] is increasing. It is expected to be compatible with GPS (Global Positioning System) [2] in L1, L2, and L5 bands and, at the same time, can provide its own services via new signals in L6 and S bands. Although the L6 and S bands are much less crowded than L1, L2, and L5 bands, interference on the legacy RNSS's is still one of the most critical issues for a new system to be adopted and deployed [3]. This paper focuses on chip pulse design for the new signals in L6 and S bands. Among many requirements for optimal pulse design, we put the intersystem interference with the legacy RNSS's at the top priority. We assume that 4 and 3 service signals with various chip rates are transmitted at L6 and S bands, respectively. The candidate waveforms of the service signals are confined to constant amplitude bipolar waveforms -BPSK (Binary Phase Shift Keying) and BOC (Binary Offset Carrier) -and we perform exhaustive search to find the best waveforms and their parameters [4]. The results presented in this paper are preliminary.
