Adaptace ochranného intervalu dle impulzní odezvy rádiového kanálu

Abstract

This thesis describes the optimization of the current methods of securing of radio transmission against the adverse effects of multipath propagation in the radio channel to increase data throughput. The means of measurement of the impulse response of real radio channel, programmed unique radio channel simulators and programmed simulators of radio communication systems are described. Next the effective means of radio channel impulse response measurement in low power endpoint devices is described from which the principle of optimization of current methods of securing of radio transmission against multipath propagation follows, in the form of adaptive length of guard interval, whereby the data throughput of radio communication system is increased in the case of good conditions of radio channel. Simulations results of the interconnected simulators with the variety of combinations of configuration parameters of radio channel environment and configuration parameters of radio communication system evaluate the effects of those parameters on the current and optimized radio communication systems quality parameters. This thesis also describes the versatility of usage of the created simulators in the electro technical industry and new radio communication technologies development.
