Modeling and Simulation of the Physical Layer of the Single Channel Ground and Airborne Radio System (SINCGARS)

In this thesis, the physical layer of the Single Channel Ground and Airborne Radio System (SINCGARS) was analyzed in order to gain insight into the bit-error-rate (BER) performance in various channel conditions. The BER performance of the radio was examined using theoretical, simulation, and experimental techniques. These results are presented in graphical form as the probability of bit error as a function of the energy per bit to noise power spectral density ratio. The results of the simulation show excellent agreement with the theory, while the experimental results deviate from theory at higher signal-to-noise levels. This suggests sub-optimal SINCGARS performance, most notably in the signal power to noise power range where reliable data transmission should take place.
