摘要 针对AMI的需求和有线/无线系统各自的不足,提出了一种适用于AMI的有线无线融合的数据传输系统及方法。该系统将有线传输和无线传输有机地结合起来,实现了系统与环境和信道特性相适应的传输方案的灵活选择;采用OFDM技术,增强了系统的抗干扰性能,提高了数据传输率;通过多种调制模式的设计,使系统在可靠稳定的前提下拥有尽可能高的速率;通过有线无线的基带复用,简化了系统设计,节约了系统成本。 Aimed at meeting the needs of AMI and improving the existed wired/wireless system, a system and method applying to AMI of integrated wired/wireless data transmission are posed. Combining wired transmission with wireless transmission, this method improves the transmission system so as to ensure that the system is suitable for the environment and channel characteristics. Adapting the OFDM technique, the system improves its anti-interference ability as well as data transmission rate. What’s more, designed in a way of adaptive selecting of multiple modulation models, the system possesses a transmission rate which is as high as possible on the reliable and stable precondition. Meanwhile, adapting the fully reuse of wired/wireless baseband, the system is much simply designed thus cuts the cost of the system.
