说明：：针对正交频分复用－无源光网络（ＯＦＤＭ－ＰＯＮ）传输系统中的数据安全与高峰均功率比（ＰＡＰＲ） 问题，提出一种基于混沌映射的ＰＡＰＲ降低与数据加密算法。该加密算法，首先利用拉格朗 日多项式隐藏混沌映射初值实现密钥保护；然后，利用混沌映射生成二值序列，通过正向异或与 反向异或对明文进行加密得到动态密文，以抵抗选择明文攻击；最后，采用混沌加密的恒包络零 自相关（ＣＡＺＡＣ）矩阵与ＯＦＤＭ 符号相乘降低ＰＡＰＲ。实验结果表明，该加密算法可实现密钥的 隐藏，且生成的动态密文能够有效抵抗选择明文攻击。同时，相较于普通的ＯＦＤＭ－ＰＯＮ系统，该 算法能够实现～２．４ｄＢ（ＰＡＰＲ＝１０－３）的ＰＡＰＲ降低与～１ｄＢ（ＢＥＲ＝１０－３）的接收灵敏度提升，进 一步提升了传输性能。

说明：MIMO Wireless system is a key technology in next generation wireless communications offers significant increase in data throughput and link range without additional bandwidth or increased transmit power.The use of OFDM causes high peak-to-average power ratio. This results in power inefficiency, hence expensive radio frequency amplifiers are to be employed at the base stations. In this project, a novel OFDM based downlink Multi-User MIMO system is proposed. Here the multi user precoding,OFDM modulation and PAPR reduction will be performed jointly. A fast iterative truncating algorithm will be developed to achieve low PAPR.

说明：orthogonal frequency division multiplexing (OFDM) is the most popular modulation technique in modern wireless communication systems. Even though there are many advantages of OFDM, it has two main drawbacks: High peak-to-average power ratio (PAPR) and frequency offset. In this paper the issue of PAPR in OFDM is discussed. Due to the large number of subcarriers used, OFDM systems have a large dynamic signal range with a very high peak-to-average-power ratio (PAPR) which makes OFDM sensitive to nonlinear effects.
