چکیده
In a fast fading channel, the orthogonality of the two consecutive Space Time Block Codes (STBC)-Orthogonal Frequency Division Multiplexing ( OFDM) symbols will be destroyed and the received signals cannot be perfectly separated. TR(Tone Reservation) is a technique designed to combat this problem by reserving a number of carries(tone) in the frequency domain to generate a cancellation signal in time domain to remove high peaks. In order to increase performance of Tone reservation method, Space Time Block Code is introduce .We evaluate the performance of Orthogonal Frequency Division Multiplexing systems under the combined influence of Tone Reservation and Space Time Block Codes in ML(Maximum-Likelihood ) estimation using BPSK(Binary Phase Shift Keying) Modulation is presented .The theoretical analysis as well as MATLAB (Matrix Laboratory) simulation result indicated that the CCDF (Complementary Cumulative Distribution Function) curve cause of the original algorithm in the reduction for the PAPR Peak to Average Power Ratio of Orthogonal Frequency Division Multiplexing System signal.

Selective Tone Reservation Method for PAPR Reduction of Spatially Multiplexed OFDM Systems
Tone Reservation (TR) is one of the well-known methods for PAPR reduction of Orthogonal Frequency Division Multiplexing (OFDM) systems. In this method some sub-carriers are reserved for PAPR reduction and the symbols in these sub-carriers are selected such that the PAPR of the OFDM frame is minimized. In this paper, the iterative algorithm introduced earlier for TR method in single antenna OFDM...

The high Peak to Average Power Ratio (PAPR) of Orthogonal Frequency Division Multiplexing (OFDM) and MIMO-OFDM systems reduces the system efficiency. In this paper, an extension of Tone Reservation (TR) method is introduced for PAPR reduction in Space Frequency Block Coded OFDM (SFBC-OFDM) systems. The proposed algorithm is based on a time domain kernel which is added to the signal of the anten...

In this paper a method that mixes tone reservation (TR) techniques and phase information of the pilot tones to efficiently reduce the peak to average power ratio (PAPR) of the multiple input multiple output (MIMO) orthogonal frequency division multiplexing (OFDM) signals is presented. First, we utilize convex optimization techniques to design dummy symbols to unused or reserved set of subcarrie...
متن کاملPAPR Reduction of OFDM signals using Tone Reservation Technique
Orthogonal frequency division multiplexing (OFDM), has recently attracted considerable attention because of its features to combat delay spread or frequency selective fading of wireless or wireline channels. One of the major drawbacks of OFDM is the peak-to-average power ratio (PAPR) which leads to an inefficient use of high power amplifiers (HPA) in communications systems. This paper present t...
