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

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.
