摘　　要：在简单介绍了差分空时分组码(DSTBC)技术的基础上,结合未来高速超短波跳频电台的发展情况和特点,对DSTBC在未来高速超短波跳频电台中应用的可行性进行了研究和探讨。理论及仿真结果表明,工作为300MHz频率,天线间距0·3m的双天线跳频电台采用差分空时分组码后,其性能增益为12dB,在复杂度增加不多的情况下,大大提高了抗衰落性能。The paper introduces the technology, of DSTBC first, then studies its application in future high speed VHF/UHF frequencyhopping radios based the characteristics of high speed VHF/UHF frequency-hopping radios. The theory and the simulation result indicate that for a dual-antenna frequency-hopping radio with operation frequency of 300MHz and a distance of O. 3m between the two antennas, the application of DSTBC technique may achieve a performance gain of about 12dB. With this technique, the anti-fading performance is improved greatly without much increase of complexity.
