| 摘 要： | 针对TDDM调制信号独有的基带信息扩频特性,采用通常的方法无法达到正确捕获的目的。为此,针对TDDM调制信号特性,提出了一种捕获判决新方法;通过初捕判决处理确定当前积累时间内的扩频方式,而且,通过k系数判决去除扩频方式的模糊性。通过仿真测试验证了此方法的有效性。

| Abstract: | The aim of accurately acquisition wouldn’t been achieved,based on the spreading spectrum characteristic of TDDM modulation signal.A new judge method of acquisition TDDM modulation signal was proposed.The mode of spreading spectrum was identified by original judging,further more the illegibility of spreading spectrum was removed by k coefficient judging.The validity of this method was proved in the simulation condition. |

| Keywords: | TDDM original judging k coefficient judging simulation |
