Analysis and Comparison of PAPR Reduction Techniques in OFDM Systems
The destructive impact of fading environments and also bandwidth limitations are two main challenges which communication is dealing with them. These challenges can affect on the growth of wireless communication and even cause reliable communications and high data rate to be prevented. Thus, OFDM (Orthogonal Frequency Division Multiplexing) modulation by using of fast calculation hardwares such ...
متن کاملPAPR Reduction Performance for LTE OFDM Systems with Different Techniques
Orthogonal Frequency Division Multiplexing (OFDM) is one of the Strong candidate for Transmission of high data rate due to Multicarrier Modulation. One of the challenging Issue of OFDM is its high Peak to Average Power Ratio (PAPR) which cause large number of sub-carriers, that make restrictions for practical applications. This Paper discusses different PAPR Reduction techniques in OFDM. The Se...
متن کاملA Low Complexity Forward Error Correction for PAPR reduction in OFDM Systems
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...
متن کاملOverall PAPR Reduction for MIMO OFDM Systems
Multiple Input Multiple Output (MIMO) Orthogonal Frequency Division Multiplexing (OFDM) systems have been receiving a great attention as one of the solutions for achieving high speed, efficient, and high quality of service wireless communications. However, the main drawback of MIMO OFDM systems is high Peak to Average Power Ratio (PAPR) because of its sensitivity to the nonlinear distortions in...
متن کاملLow-complexity Pts-based Schemes for Papr Reduction in Sfbc Mimo-ofdm Systems
The systems which have the high peak-to-average power ratio that is OFDM systems which degrades the performance of the amplifier. To overcome this, various distortion and distortion less algorithms are suggested. The Partial Transmit Sequence (PTS) is the technique that is distortion less which separates the sequences of input to the subsequences and selects minimize optimized PAPR in the signa...
