Abstract


A telemetry transmission system is described. This system appeared as a model which was used to check the propagation conditions and the noise immunity of the transmitted signal. Based on the obtained data a modeling was performed in the MATLAB environment in order to realize a better degree of noise immunity of the given signal. With this aim after the upgrade of the hardware part of the encoder the use of the simplest and the most noise immune codes (15/11 Hamming) and checking its work under the influence of the pulse interference were suggested. The results coincided with the theoretical estimations.
