Individual students will have a semester research or applied project in a European service organization,being supervised by a lecturer or a researcher from each universities.It is expected that graduates will understand technological,organizational and cultural aspects of the diverse businesses in a wide European context and will be ready for service requirements of this century.展开更多

广义SSME算法(GSSME:Generalized Split-Symbol Moment Estimator)是在SSME算法的基础上把每个符号均匀分成多段而得来的。本文提出了复数加性高斯白噪声中基于迭代GSSME算法的MPSK信号盲信噪比估计算法,推导了每符号采样点数和分段数...广义SSME算法(GSSME:Generalized Split-Symbol Moment Estimator)是在SSME算法的基础上把每个符号均匀分成多段而得来的。本文提出了复数加性高斯白噪声中基于迭代GSSME算法的MPSK信号盲信噪比估计算法,推导了每符号采样点数和分段数之间的关系。分别对BPSK、QPSK和8PSK信号进行了计算机仿真,并与常规SSME算法进行了比较。结果表明当信噪比高于一定值时,迭代的GSSME算法能达到更小的偏差和均方误差,并且估计性能与MPSK信号的调制阶数M无关。展开更多
