  • Abstract
    In this paper performances of algorithm for improvement of PAPR parameter of 16-QAM OFDM signals were analyzed. By implementation of algorithm constellation diagram of OFDM signal is dynamically changing, and it does not require transmitting information about it to the receiver. Decision metric of algorithm is based on simple mathematical tool what improves efficiency. Computer simulations in MATLAB confirmed success in reduction of PAPR parameter.
