On this page, you will learn how to become a Singapore Permanent Resident (PR) under the Professional, Technical Personnel, and Skilled Workers Scheme (PTS Scheme). The Professional, Technical Personnel, and Skilled Workers scheme (PTS Scheme) is designed to allow individuals holding a Singapore ...
The numerical calculation and simulation results show that the proposed PTS approach can reduce the computational complexity while achieving the same PAPR reduction when compared to the conventional PTS scheme. The results also show that PSO based PTS provides more improved PAPR reduction performance....
A new partial transmit sequence (PTS) scheme with low computational complexity is proposed, where two search steps are taken to find a subset of phase rotating vectors showing good peak-to-average power ratio (PAPR) reduction performance. In the first step, sequences with low correlation are ...

After that the proposed scheme utilizes the conventional PTS technique to further reduce the PAPR of the OFDM signal. The performance of the PAPR is evaluated using a computer simulation. The simulation results indicate that the proposed scheme may improve the PAPR performance compared with the ...
The simulation results show that the performance of the proposed RVGA PTS, along with an extinction and immigration strategy, provides approximately the same PAPR statistic as the exhaustive PTS scheme, while maintaining a low computational load./p...
目前暂无任何一种半导体能同时满足该要求;但实验研究发现通过采用类似“堆积木”的方式构建异质结,可以提高体系的光催化性能。目前实验已发现具有高效光催化潜能的异质体系包括 II 型、Z 型和 S 型 (S-Scheme) 异质结。 因此,如何设计制...
