| 摘 要： | 使用Ka频段是卫星通信系统解决信道拥挤和提高系统容量的有效途径.为了提高Ka频段卫星通信的传输性能,本文在对Ka频段固定卫星通信信道进行分析的基础上,提出了一种适合该信道的Turbo码编译码方案,译码时通过使用修正的信道可靠性常数极大地提高了译码性能.最后,利用Ka固定卫星通信信道模型对该Turbo码方案性能进行了仿真.仿真结果表明,本文采用的Turbo码方案与采用相同码率的卷积码和卷积级联码方案相比,所带来的增益大于1.5 dB.

| Abstract: | Moving to Ka-band is an effective way of solving closed orbits and improving system capacity for the satellite communication.Based on the analysis of Ka-band fixed satellite communication channel,a Turbo coding scheme is present suit for the channel,having better performance improvement through using optimized channel constant.A model of Ka-band fixed satellite communication channel and a corresponded simulation system with the Turbo coding scheme are created.Simulation results show that the Turbo coding has more 1.5dB gain than convolution coding or convolution concatenated coding. |
