Widely-Linear Selected Mapping for Peak-to-Average Power Ratio Reduction in OFDM
نویسنده
چکیده
Peak-to-average power ratio reduction in OFDM using selected mapping (SLM) is considered. A new low-complexity version of SLM is introduced, which employs the principle of widely-linear signal processing, i.e., real and imaginary part of the candidate OFDM frames are treated separately. Thereby, investing the numerical complexity of conventional SLM with U candidates, a performance almost equal to U2 candidates can be obtained with widely-linear SLM. Numerical simulations cover this performance. This work was supported in parts by Deutsche Forschungsgemeinschaft (DFG) within the framework TakeOFDM under grant FI 982/1-1.

An Efficient Scheme for PAPR Reduction of OFDM based on Selected Mapping without Side Information
Orthogonal frequency division multiplexing (OFDM) has become a promising method for many wireless communication applications. However, one main drawback of OFDM systems is the high peak-to-average power ratio (PAPR). Selected mapping (SLM) is a well-known technique to decrease the problem of high PAPR in OFDM systems. In this method, transmitter is obliged to send some bits named side informati...

In this paper, a Peak to Average Power Ratio (PAPR) reduction technique in Orthogonal Frequency Division Multiplexing (OFDM) systems is proposed. This technique uses error correction capability of channel coding to reduce the PAPR.The coded bits at the input of OFDM modulator are separated into two groups of the Most Significant Bits (MSB) and the LeastSignificant Bits (LSB). The bits are mappe...

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...

متن کاملPeak to Average Power Ratio (papr) Reduction Techniques for Ofdm-mimo System
In the previous chapter, to get high data rate transmission, High Throughput techniques were analyzed for OFDM-MIMO System. OFDMMIMO systems based on OFDM symbols suffer from the problem of inherent Peak to Average Power Ratio (PAPR). The peak power of a multi carrier OFDM signal is a critical design factor for band limited communication systems, and it is necessary to reduce it as much as poss...
