Abstract
This paper deals with GMSK and 4-Level FSK modulation schemes which are adopted in the land mobile services. The analysis of group delay interaction has been carried out by approximative mathematical reflections. Better spectral efficiency, achieved together with keeping up good energetic efficiency, can be the result of the above analysis. Many current and proposed mobile data transfer applications would provide a better service, and be more spectrally efficient, if the data rates could be increased.
