Abstract
Modeling and simulation of communications systems is an efficient and fast way to highlight the performance and the main design difficulties of the latter. The experience and the real measure are still indispensable tools for the validation of the simulation results and its improvement.
Our work consists of real experience of satellite transmission/reception. The experience was done in the national society of radio and television, where we measured and compared the transmitted and the received signal by changing the parameters at the input such as power, frequency, type of coding and modulation.
In these experiences, we used a GSERTEL tool as measurement system in order to show the performance according to gain and emission power. As result, we have different types of parameters (C/N, MER BCHBER, LDPCBER, EIRP, Constellation and Link margin).
In this paper, we present the main characteristics of satellite transmission/reception and the description of modulation, demodulation, and the encoding types. These characteristics have been experimented and measured by doing a transmission with different frequencies within the National Broadcasting and Television Company, where we have transmitter and receive some data with different parameters. Finally, obtained results are evaluated, compared and discussed.
