Socp Approach for Reducing Papr for Mimo-ofdm via Tone Reservation

A combination of multiple-input multiple-output with orthogonal frequency division multiplexing has become a promising candidate for wireless communications. However, like OFDM, a serious disadvantage of the MIMO-OFDM system is the high Peak to Average Power Ratio (PAPR), which may severely affected the power efficiency of RF power amplifiers. In this paper, we proposed a novel method to reduce...

Selective Tone Reservation method for PAPR reduction in SFBC-OFDM systems

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...

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...

PAPR Reduction Scheme with SOCP for MIMO-OFDM Systems

Combination of multiple-input multiple-output (MIMO) with orthogonal frequency division multiplexing (OFDM) has become a promising candidate for high performance wireless communications. However one major disadvantage of MIMO-OFDM systems lies in a prohibitively large peak-to-average power ratio (PAPR) of the transmitted signal on each antenna. In this paper we extend from SISO to MIMO systems ...

PAPR reduction scheme with selective tone reservation for OFDM signals

In this paper, we propose a peak-to-average power ratio (PAPR) reduction scheme with selective tone reservation. In this scheme, the preset peak reduction tone (PRT) set would be divided into M PRT subsets that can generate M time-domain kernels. The differences of the slopes for the phase responses of the M timedomain kernels would be considered to design the M PRT subsets in reducing the PAPR...
