  Waveform generation is essential for studying signal propagation and channel
characteristics, particularly for objects that are conceptualized but still
need to be operational. We introduce a comprehensive guide on creating
synthetic signals using channel and delay coefficients derived from the
Quasi-Deterministic Radio Channel Generator (QuaDRiGa), which is recognized as
a 3GPP-3D and 3GPP 38.901 reference implementation. The effectiveness of the
proposed synthetic waveform generation method is validated through accurate
estimation of code delay and Doppler shift. This validation is achieved using
both the parallel code phase search technique and the conventional tracking
method applied to satellites. As the method of integrating channel and delay
coefficients to create synthetic waveforms is the same for satellite, HAPS, and
gNB PRS, validating this method on synthetic satellite signals could
potentially be extended to HAPS and gNB PRS as well. This study could
significantly contribute to the field of heterogeneous navigation systems.
