| 摘 要： | 遥测信道是一种典型的时变衰落信道,为弥补信道衰落对信息传输质量的影响,通常采用纠错编码的方法比单纯依靠加大系统功率裕量的方法更有意义。根据RS码的相关理论及编译码原理,结合遥测信道的特点,提出了RS码与卷积码级联的编译码方案,最后对该级联码的方案进行了软件仿真和硬件设计。实现结果表明级联码的增益要优于单纯的卷积码2 dB。

| Abstract: | The telemetry channel is a typical time-varying and fading channel.For the purpose of compensating the information quality in the receiver,the method of error-coding is more significant than increasing system power.Based on the theory of RS code and the characteristics of the telemetry channel,the concatenated code scheme of RS code and convolution code was put forward.The scheme was simulated and its hardware was designed.The result shows that the gain of the concatenated code is larger than that of the co... |
