选择映射法(SLM)和概率类算法都可以降低OFDM (Orthogonal Frequency Division Multiplexing)系统的PAPR(peak to Average Power Ratio),传统SLM算法自身较为复杂,但由于其优良的性能,弃之可惜。研究表明,SLM算法和限幅类算法在性能上具有一定的互补性。任何一个算法未必能达到抑制PAPR的理想效果,在深入研究了两个算法的基础上,将其优点联合起来,以达到降低OFDM系统PAPR的目的。最后对联合改进算法进行了分析与仿真,并验证了联合改进算法的有效性和可行性

Basic function to locate and measure the positive peaks in a noisy data sets. Detects peaks by looking for downward zero-crossings in the smoothed third derivative that exceed SlopeThreshold and peak amplitudes that exceed AmpThreshold. Determines, position, height, and approximate width of each peak by least-squares curve-fitting the log of top part of the peak with a parabola.

This paper describes a bus mastering implementation of the PCI Express protocol using a Xilinx FPGA. While the theoretical peak performance of PCI Express is quite high, attaining that performance is a complex endeavor on top of an already complex protocol. The implementation is described and its performance is analyzed. Source code is offered for free download via the web.
