| 摘 要： | 虽然OFDM调制技术在射频领域中已得到了广泛的研究,但在无线光领域中的研究才刚开始.由于FSO-OFDM系统中采用马赫-曾德尔(MZM)调制器进行电光转换,该调制器的转移特性曲线为余弦函数,存在很大的非线性问题,因此,FSO-OFDM系统比射频OFDM系统对PAPR更加敏感.为了降低系统PAPR,重点研究了基于Gola...

| Abstract: | Although the OFDM modulation technique has been studied extensively in radio frequency(RF) field,it is just beginning in the field of free space optical communication.The Mach-Zehnder modulator(MZM),whose transfer characteristic curve was cosine function,was adopted to achieve electro-optic conversion in the FSO-OFDM system.Due to its big non-linear problem,so FSO-OFDM system was more sensitive to the PAPR than RF system.In order to reduce the PAPR,the algorithm which based on the Golay complementary sequen... |
