摘要
为扩大散射信道传输容量和提高其传输效率,在多种时钟业务传输过程中,可采用多业务异步复分接技术。根据极低速散射通信系统的特点,在进行业务复分接时为了改善帧同步,论文提出使用Turbo码帧同步算法,该算法不需要插入任何导频符号,利用信道码字特征和译码的迭代信息辅助系统完成帧同步,提高了系统的帧同步精度及传输效率。
In order to expand the transmission capacity and improve the transmission efficiency of the scattering channel,the multi-service asynchronous multiplexing and demultiplexing technology can be used during the service transmission with multiple clocks.According to the characteristics of ultra-low rate scattering communication system,in order to improve frame synchronization in the process of carrying out service multiplexing and demultiplexing,the paper proposes to use Turbo code frame synchronization algorithm,which does not need to insert any pilot symbols and uses the channel code word characteristics and iterative information of decoding to assist the system to complete frame synchronization,so as to improve the frame synchronization accuracy and transmission efficiency of the system.
