摘要
针对TDMA跳频系统的通信特点,提出一种频率自适应选择方法.该方法利用周期性统计跳频系统频带内各频点业务量的接收情况,对各频点是否受到干扰进行判定,确定通信环境中的干扰频点,并依此选择更新系统所使用的频率集,完成实时的选频和换频工作,使系统初步具备对无线通信中电磁环境的感知能力.通过实验数据对比分析,结果表明该方法有效地提高了系统数据传输质量,增强了系统的抗干扰性能.
In this article a frequency adaptive selection method is proposed according to the communication peculiarity of the TDMA frequency hopping system.The disturbed frequency in communication environment will be confirmed by periodically statistic the operation reception of all frequency band,and the using frequency aggregate will be updated base on the operation reception,the hopping system accomplish the choosing and replacing frequency work in real time,and this method make the hopping system have some radio communication environment perception capability.The result of comparing experiment data analysis shows that this method can improve the data transmission quality,and enhance the anti-jamming capability effectively.
