CBOC performances using software receiver

Abstract : MBOC(6,1,1/11) [1] has been identified as a promising modulation for the optimisation of Galileo E1 OS and GPSIII L1C. The corresponding power spectral density is the combination of BOC(1,1) and BOC(6,1) PSD and a number of modulations lead to the targeted power spectral density. One of the solution, that seems to be the favourite candidate for Galileo, is the Composite BOC (CBOC). It adds linearly the BOC(1,1) and BOC(6,1) waveform creating a multi-level waveform. Several more or less complex receiver's architecture can be used to track CBOC signals offering different performances in various degraded environment. The theoretical performances of CBOC have already been presented in several articles. The aim of this article is to asses CBOC performances for a number of receiver architectures implemented in a software receiver. The first step consist in generating CBOC signal using a software generator and it was considered as a second step to generate CBOC signal using a RF signal generator.
