基于MSP430单片机的窄带无线数据传输模块的设计

摘要

Aiming at the boundedness of analog channel of narrowband radio station in the process of data transmission,a narrowband wireless data transmission module based on MSP430 was designed. The basic parts of the narrow-band wireless data transmission module structure and the design scheme of the partial hardware/software design technology are analyzed,especially in the fields of communication circuit,data processing,MDM,transmission distance,power management and anti-jamming. Moreover,it makes full use of the main characteristics of MSP430 series MCU functions. It achieved high speed data communi-cation on SW or USW narrowband wireless analog channel,increased the speed,capacity and reliability of information transmis-sion. It plays an important guiding role in application and development of narrowband wireless data communication system.%针对窄带无线电台模拟信道传输数据信息所存在的局限性问题,研究设计了基于MSP430单片机为核心的窄带无线数据传输模块,充分利用MSP430系列单片机的主要特点功能,分析研究窄带无线数据传输模块的基本组成结构和部分硬软件设计技术方案.在通信电路、数据处理、调制解调、电源管理和抗干扰及传输距离等方面做了较深入的研究探析,实现在短波、超短波窄带无线电台的模拟信道上进行较高速率的数据通信,提高了信息传输的速度,增大了信息传输的容量,增强了信息传输的可靠性,为窄带无线数据通信系统的研究应用及发展提供了重要的指导作用.
