This paper presents an efficient peak to average power ratio (PAPR) reduction schemes for a multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) based cognitive radio (CR) network. The proposed scheme makes use of a constrained adaptive Markov chain Monte Carlo (CAMCMC) technique to select peak reduction tones (PRT) for the tone reservation (TR) technique. The CAMCMC...
