Abstract
In this paper, Code-Shift-Keying (CSK) is investigated in combination with Forward Error Correction (FEC) coding techniques, with an additional block interleaving scheme. The target of this analysis is to evaluate the CSK capability to increase data rate or data demodulation sensitivity in GNSS scenarios as compared to the use of traditional BPSK A particular set of advanced signal baselines is reported as example of application to SBAS signal formats, assessing the data delivery performance in Additive White Gaussian Noise (AWGN) channel, two-ray multipath and Land Mobile Satellite (LMS) channel in terms of Bit Error Rate (BER).
