| Popis: | International audience; This paper focuses on the demodulation performance analysis of different CSK configurations coupled with different demodulation/decoding methods in urban environments. The tested CSK configurations are defined by the number of bits mapped by a CSK symbol, the number of PRN codes constituting a symbol, and the codeword source mapping. The tested demodulation techniques are the traditional non-coherent demodulation technique and a new proposed technique called ‘non-coherent PRN code’ which reduces the demodulation exposition to the carrier phase fast variations. The tested scenarios depend on the mobile speed and the Line-of-Sight received signal conditions. From all these parameters, a better overall view of the behavior of a CSK signal transmitted in urban environments is obtained and more tools are provided for the design of a GNSS CSK modulated signal |
