无线电同址干扰定量分析方法研究

针对同址干扰对车载通信系统的影响,提出了定量分析模型。首先,对功率耦合度进行了理论和实验分析,特别是对接收机的干扰抑制性能进行了研究。通过对常用的调制、编码、交织模式的分析,建立了误码率计算函数库,作为调用子模块。为了验证定量分析模型的准确性、有效性,基于需求分析构建了有线实验平台。结果表明:理论和实验结果相符,模型的建立为配置电台工作参数,设计通信系统奠定了基础。

Quantitative analysis on radio co-site interference

For the co-site interference effect on vehicular communication system,a quantitative analysis model is proposed.Firstly,the coupling degree of power is analyzed from experiment and theory,especially the interference suppressed performance of receiver is studied.Then,through analyzing the patterns of the modulation,encoding and interleaving,the computing function library of bit error rate(BER) is established,which is used as a sub block.To verify the accuracy and validity of the quantitative analysis model,a wired experiment platform based on the requirement analysis is established.Study indicates that the theoretical and experimental results are consistent,and this model is the foundation in designing communication system and arranging parameters of radio communication.
