摘要
数字电视广播-数字卫星新闻采集标准(DVB-DSNG)把实用网格编码调制(P-TCM)作为可选的内编码和调制方式,在保持信息速率且不增加带宽的情况下提高功率利用率。本文针对DVB-DSNG系统,提出了一种P-TCM解码器的设计方案,根据计算机仿真结果对算法的参数进行了优化,并在FPGA上进行了设计的验证。
DVB-DSNG Standard employs P-TCM as an optional inner coding and modulation scheme to attain energy efficiency under the condition of maintaining the information rate and with no need to extend the bandwidth. Focusing on the DVB-DSNG system, this paper presents a design scheme for P-TCM decoder with optimal parameters determined through computer simulation and verified on FPGA.
