| 摘要: |
| 在多径传播信道中，因多径衰落导致的随机相位和幅度干扰会影响信号的接收效果，并且接收机和发射机都需要精确的频率参考，在此基础上发展起来的透明带内导音(TTIB)技术可以满足抗多径衰落与克服频率漂移的要求。以往的TTIB处理大多是利用DSP芯片来实现的，而本文对用FPGA这一新的方法来实现TTIB处理进行了探讨，并在EDA平台上理论地实现了THB的处理．从而说明基于FPGA平台也能有效地实现TTIB处理，并且在速度、灵活性以及成本上都具有优势。 |

| Abstract: |
| The effect of random amplitude and phase fluctuation on the received signal through severe multipath propagation conditions, as well as the need for precise frequency reference in both the transmitter and receiver, has led to the inception and development of Transparent Tone in Band(TTIB). Before then, most realizations of application of TTIB were based on DSP chips. In this paper, the realization of TTIB based on FPGA is discussed. The results demenstrate that this measure can realize the application of TTIB efficiently. At the same time, it is preferable in speed,agility and cost. |
