Abstract :
In mobile radio systems the effects of fading can be counteracted by the use of diversity techniques either at the base station or the mobile. Since reducing fading, diversity schemes contribute to the reduction of the bit error rate that degrades the performance of any modulation scheme. This paper attempts to determine the performance of a typical TETRA system, without diversity for a variety of operating conditions and environments. This will provide a benchmark for assessing any benefits that diversity techniques will bring. Also it aims to find the limits of performance that can be achieved by using a two-branch space diversity system on a TETRA radio channel
