| 摘 要： | 数字电视广播的数字卫星新闻采集标准(DVB-DSNG)采用RS码和P-TCM编码分别作为可选的外码和内码,QPSK以及高阶调制(8PSK,16QAM)作为调制方式,在保持信息传输速率且不增加带宽的情况下提高频谱利用率。针对DVB-DSNG系统,在P-TCM编解码器基础上,设计了实时基带信号调制解调器,通过仿真,在FPGA上进行了设计的验证。

| Abstract: | DVB-DSNG Standard employs RS code and P-TCM code as an optional outer and inner coding,QPSK and higher order modulation(8PSK,16QAM) as the modulation scheme to attain energy efficiency under the condition of maintaining the information rate with no need to extend the bandwidth.Focusing on the DVB-DSNG system,a design scheme for real-time base band modem is presented based on P-TCM codec with optimal parameters determined through computer simulation and verified on FPGA. |
