摘要
光纤毫米波系统中,各个基站通过光纤连接,而毫米波用光学方法产生,所以光纤毫米波技术更适合于毫米波传输。文中提出了一种新型的光纤毫米波技术,光学倍乘法。通过对该系统进行理论分析和仿真试验,表明光学倍乘法可以有效简化系统结构、降低成本。同时把三角波扫频改为锯齿波扫频后,不仅可以抑制多余的谐波分量,而且更容易实现。
Radio over Fiber technology is more suitable for millimeter wave transmission, with this technology, the base stations are connected with optical fiber and millimeter wave is produced by optical method. In the paper,a new Radio over Fiber technology, optical frequency multiplying system, is presented. The analysis and simulation show that the method can simplify the system structure and reduce the cost. Furthermore tooth wave sweep is easier to realize than triangle wave sweep and can also restrict the harmonious elements.
