本文提出一种用m序列的平移等价序列做指令的遥控系统。利用m序列的自相关函数具有双值特性的这一特点,可使指令自动纠错,而不增加设备的复杂程度。文中对系统的理论根据作了说明,列出基本公式。然后介绍工作原理,给出有关电路,用7级移住寄存器集成电路产生同一m序列的7个平移等价列序,各寄存器的输出端按7条指令的规律连接、收端用7个匹配滤波器做相关器,通过判决电路进行择大判决,并输出相应的指令至执行机构。 This paper presents a remote control system that uses m-sequence translation equivalent sequences as instructions. Using the feature of the dual-valued nature of the autocorrelation function of the m-sequence allows instructions to be automatically error-corrected without increasing the complexity of the device. In the paper, the theoretical basis of the system is described, listing the basic formula. Then introduce the working principle, given the circuit, with 7 shift register integrated circuit to produce the same m sequence of 7 translation equivalent sequence, the output of each register according to the rules of the seven instructions, the receiver end with seven matched filter Do correlator, through the decision circuit to choose the big decision, and output the corresponding instructions to the implementing agencies.
