多径衰落下符号定时恢复算法的改进

An Improved Algorithm for Symbol Timing Recovery in a Multipath Fading Channel

该文提出了在多径衰落信道环境下、宽带数字电视地面广播BDB-T系统中符号定时恢复的改进新算法,导出了计算公式并设计了相应的FPGA硬件电路,计算机仿真及在高清晰度数字电视功能样机上的调试证明了改进算法的优良性能。

This paper proposes a new improved algorithm for symbol timing recovery in a multipath fading channel through computer simulations. The computing equation is derived. Also, the correspondent FPGA hardware circuit is designed. Computer simulations and the testing process in the HDTV prototype prove its low complexity, easiness of realizing and excellent performance.
