REDUKCE DYNAMIKY SIGNÁLU V SYSTÉMECH S ORTOGONÁLNÍM FREKVENČNÍM MULTIPLEXEM / THE REDUCTION OF SIGNAL DYNAMIC IN ORTHOGONAL FREQUENCY DIVISION MULTIPLEX SYSTEMS

This doctoral thesis is focused into the area of multicarrier radio communications systems. These systems are perspective for current and incoming mobile communications and wireless networks. Advantages of multicarrier systems like better multipath propagation resistivity are redeemed by some disadvantages. The high peak to average power ratio of transmitted signal belongs to these disadvantages, for its inconvenience for high efficient power amplification. The thesis concerns with peak to average power ratio reduction methods for OFDM systems, that belongs to the most used multicarrier systems. One of the main objectives is the modification of the existing methods with the intention of complexity reduction. Following subject of interest is the analysis of suitable methods combinations possibilities for more significant peak to average power ratio reduction. One part of this thesis is research of influence of these methods on the OFDM signals with different parameters.
