選擇映射法（SLM）和概率類算法都可以降低OFDM （Orthogonal Frequency Division Multiplexing）系統(tǒng)的PAPR（Peak to Average Power Ratio），傳統(tǒng)SLM算法自身較為復(fù)雜，但由于其優(yōu)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(bǔ)性。任何一個(gè)算法未必能達(dá)到抑制PAPR的理想效果，在深入研究了兩個(gè)算法的基礎(chǔ)上，將其優(yōu)點(diǎn)聯(lián)合起來，以達(dá)到降低OFDM系統(tǒng)PAPR的目的。最后對(duì)聯(lián)合改進(jìn)算法進(jìn)行了分析與仿真，并驗(yàn)證了聯(lián)合改進(jìn)算法的有效性和可行性

The single-carrier frequency division multiple access (SC-FDMA) system is a well-known system that has recently become a preferred choice for mobile uplink channels. This is attributed to its advantages such as the low Peak-to-average power ratio (PAPR) and the use of frequency domain equalizers. Low PAPR allows the system to relax the specifications of linearity in the power amplifier of the mobile terminal, which reduces cost and power consumption.

This program will ask how many numbers you want to find the average of, then it will allow you to enter your numbers(yes they can even be decimals) then it will calculate the mean, median, mode and range of what you enter.
