An Improved SLM Technique For PAPR Reduction In OFDM Systems
Orthogonal Frequency Division Multiplexing (OFDM) is widely used as a standard modulation for various high data rate wireless communication systems. It is worked by converting high data rate streams into a number of parallel low data rate streams. OFDM has many advantages over single carrier modulation systems. Some of these advantages are robustness to frequency fading channels, high transmiss...
متن کاملHybrid SLM-PTS for PAPR Reduction in MIMO-OFDM
Multiple-Input Multiple-Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) is a promising candidate for 4G broadband wireless communications. However, MIMO-OFDM inherited the problem of high Peak-to-Average Power Ratio (PAPR) from OFDM. Many PAPR reduction techniques were developed in last two decades to reduce the PAPR of OFDM, among them Partial Transmit Sequence (PTS) and Selected...
متن کاملAn Overview of PAPR Reduction Technique for OFDM Signals by using Selective Mapping Technique (SLM)
Orthogonal Frequency Division Multiplexing (OFDM) is a promising technique used in the wireless broadband communication systems these days. It is a form of multi-carrier modulation technique. High spectral efficiency, robustness to channel fading, immunity to impulse interference, uniform average spectral density, capacity to handle very strong echoes and very less nonlinear distortion are the ...
متن کاملNovel Papr Reduction Technique by Combining Slm with Clipping and Filtering Technique for Mimo-ofdm System
Increased demand of multimedia system applications leads to high speed transmission speed that may be gratified by OFDM (orthogonal frequency division multiplexing). In wireless transmissions, OFDM is extremely smashing technology as it provides flexibility and high speed.One of the major drawbacks in the MIMO-OFDM is high peak-to-average power ratio (PAPR).Clipping & Filtering, Selected mappin...
متن کاملPAPR Reduction of OFDM Using a New Phase Sequence in SLM Technique
Orthogonal Frequency Division Multiplexing (OFDM) is an efficient method of data transmission. It is a base for high speed communication systems. The main drawback of OFDM system is that it suffers from high Peak – to – Average Power Ratio (PAPR). Due to high PAPR there is inefficient use of high power amplifier and this could limit transmission efficiency. OFDM consist of large number of indep...
