In real propagation environment, channel reuse causes co-channel interference which will degrade MIMO channel performance. A Successive Interference Cancellation (SIC) detection algorithm with 64-QAM technique is used to improve the quality of received signal in a high interference environment. Using Concatenating MMSE with SIC equalization, better cancellation gain can be achieved. In this pap...

Unidirectional carbon fiber-reinforced polymer nanocomposites were developed by adding alumina (Al2O3) and silicon carbide (SiC) nanoparticles using ultrasonication magnetic stirring. The uniform nanoparticle dispersions examined with a field-emission scanning electron microscope. nano-phase matrix was then utilized to fabricate the hybrid hand lay-up compression molding. weight fractions selec...

In arid and semiarid areas, the effects of afforestation on soil organic carbon (SOC) have received considerable attention. In these areas, in fact, soil inorganic carbon (SIC), rather than SOC, is the dominant form of carbon, with a reservoir approximately 2-10 times larger than that of SOC. A subtle fluctuation of SIC pool can strongly alter the regional carbon budget. However, few studies ha...

Silicon carbide (SiC) is a promising material for the preparation of high temperature membranes [1-5] due to its many unique properties such as high thermochemical stability, high thermal conductivity and resistance to abrasion. In our studies, SiC microporous membranes are fabricated using two different techniques. The first approach involves the pyrolysis of pre-ceramic polymeric films [3,4],...

The divacancy in silicon carbide (SiC) is a prominent solid state defect quantum bit that bears relatively strong fluorescence and optically detected magnetic resonance contrast (ODMR) at room temperature. These properties exemplify it for sensing of biological molecules. To this end, we previously developed top-down method to create divacancies cubic SiC nanoparticles (NPs) as non-perturbative...

Introduction: Silicon carbide is a particularly interesting phase because more than a hundred different polytypes can be formed in the laboratory. The formation of these polytypes depends strongly on growth conditions (e.g., temperature, pressure). Daulton et al. [1] used TEM to study the microstructures of ~500 presolar SiC grains in an acid residue of the Murchison meteorite (KJB fraction of ...

Increasing structural complexity at nanoscale can permit superior control over photophysical properties in the precursor-derived semiconductors. We demonstrate here the synthesis of silicon carbonitride (SiCN)/boron nitride (BN) nanocomposites via a polymer precursor route wherein the cobalt polyamine complexes used as the catalyst, exhibiting novel composite structures and photophysical proper...

With increasing interest in the carbon cycle on arid land, there is an urgent need to quantify both soil organic carbon (SOC) and inorganic carbon (SIC) thus to assess various methods. Here, we present a study employing three methods for determinations of SOC and SIC in the Yanqi Basin of northwest China. We use an elemental analyzer for both SOC and SIC, the Walkley-Black method for SOC, a mod...
