In this paper a simple test-bed to evaluate the effect of an unmodulated disrupting signal on a TETRA π/4-DQPSK (Differential Quadrature Phase-Shift Keying) signal has been developed and implemented, such that the transmitted signal does not affect other communication system existing in the same area. An unmodulated disrupting signal, with increasing amplitude, has been overlapped on the transmitted data and the parameters of the received signal has been evaluated with an Agilent Vector Signal Analyzer model 89600. Based on the results obtained, several interesting conclusions have been highlighted at the end.
