選擇映射法(SLM)和概率類算法都可以降低OFDM (Orthogonal Frequency Division Multiplexing)系統的PAPR(peak to Average Power Ratio),傳統SLM算法自身較為復雜,但由于其優良的性能,棄之可惜。研究表明,SLM算法和限幅類算法在性能上具有一定的互補性。任何一個算法未必能達到抑制PAPR的理想效果,在深入研究了兩個算法的基礎上,將其優點聯合起來,以達到降低OFDM系統PAPR的目的。最后對聯合改進算法進行了分析與仿真,并驗證了聯合改進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.
