Spectral Capacity of Frequency Hopping GSM



In the highly competitive mobile radio market the system resource spectrum is often shared between at least two system operators while the capacity and quality requirements are dramatically increasing. Random Frequency Hopping (FH) in digital F/TDMA systems like GSM and its derivatives is a method of expanding the bandwidth used by a traffic channel, thereby creating frequency and interference diversity effects. In this article, the capacity gain from the diversity effects of random FH in combination with Power Control (PC) and Discontinuous Transmission (DTX) is analyzed by means of combined link and system level simulations of the GSM full rate speech channel embedded in different network simulation environments and different network configurations.
