| 摘 要： | 乘积合并接收机以其简单有效的特性在快速跳频通信系统中得到了广泛关注。对于实际应用中普遍遇到的非最坏部分频带干扰环境,传统乘积合并算法有其自身的不足。针对这种情况,提出了一种改进的乘积合并方法,它保留了传统乘积合并算法的主要特征,通过增加对各跳频信号能量差异的检测信息,改善了传统乘积合并接收机在部分频带干扰下的传输性能,仿真验证了这种改进合并方法的有效性。

| Abstract: | The product-combining receiver has been employed widely in fast frequency-hopped binary frequency-shift-keying(FFH/BFSK) due to its effectivity and simplicity,but it has some deficiencies under the condition of non-worst-case partial-band noise jamming(PBNJ) which is more popular in practical applications.For this circumstance,we have proposed a modified productcombing receiver which not only possesses the main characteristics of traditional product-combing receiver but also improves the rejection performan... |
