摘　　要：介绍了一种以MCU为主要核心的火控系统的软硬件设计,着重讨论了满足该系统要求的FEC(前向纠错)设计方案,最终选择了RS码+CRC(循环冗余校验)的信道编码,并分析了误码性能,证明其能满足系统要求。采用ATmega128单片机实现了文中提出的设计方案,在原始误比特率为10-3的信道上,实现了误比特率低于10-10的可靠通信。This paper introduces the hardware and software design of a kind of firepower control system based on MCU chip, especially discusses on its FEC scheme. Finally, the scheme used RS ＋ CRC is selected and the decode performance is analyzed. The scheme is proved to be satisfying the system requirement. It is realized with ATmega128 MCU. The reliable communication with BER of 10^- 10 is achieved in channel with 10^-3 original BER.
