The SLM algorithm has high computational complexity for reducing the PAPR of the OFDM system.

Traditional SLM is a method to greatly reduce the high PAPR of OFDM system,but it can not avoid appearance of high PAPR completely.

By inserting bit labels, we combine convolutional code and traditional selective mapping (SLM), and propose a novel scheme to reduce PAPR.

Preparation of SLM Intravenous Emulsion;

Sphere-linear Map (SLM) , as a novel technique for data mining, was proposed to build the qualitative structure-activity relationship (qSAR) model for a series of 17 triazole-derivatives.

The carrier for the loading of the filter is a spatial light modulator(SLM)and the locating precision of this method can reac.

A novel laser printing system has been fabricated for digital optical variable image device(DOVID) based on spatial light modulator(SLM) and holographic interferential optical head.

The unit structure on the template is inputted by the spatial light modulator(SLM),exposed on photo-resist plate through the projection optical system section by section.

Using digitalized laser printing system with the spatial light modulator (SLM)used as the sub-image input device,2D optical variable devices and letters are stored in the plane recording medium photoresist,which can be made into easily reproduced relief phase hologram.

In order to reduce the high PAPR,Selective Mapping (SLM) and the improved algorithm are introduced and simulated them with MATLAB.

PAPR reduction of OFDM system by SLM;

Focused on the problem that the orthogonal frequency division multiplexing system has a large peak-to-average power ratio (PAPR), the basic principle and realization model of selected mapping (SLM) were analyzed, and the algorithm of using standard arrays of linear block codes to reduce the PAPR was proposed.
