Estudio y comparación en eficiencia espectral y probabilidad de error de los esquemas de modulación GMSK y DBPSK Studying and comparing spectrum efficiency and error probability in GMSK and DBPSK modulation schemes

Gaussian minimum shift keying (GMSK) and differential binary phase shift keying (DBPSK) are two digital modulation schemes which are -frequently used in radio communication systems; however, there is interdependence in the use of its benefits (spectral efficiency, low bit error rate, low inter symbol interference, etc). Optimising one parameter creates problems for another; for example, the GMSK scheme succeeds in
