THERMOELECTRIC POWER IN (Gd,Sm)1.85Ce0.15CuO4 SYSTEM

Thermoelectric power measurements are reported for seven samples with different x in the Gd_1.85-xSm_xCe_0.15CuO₄ system at temperatures ranging from 80K to 300K. For Sm-rich superconducting samples, thermoelectric power S has a small negative value and is almost temperature independent. As the content of Sm decreases, the absolute value of S increases and a broad valley appears in the S(T) curve. The results which can be interpreted in terms of a two-channel model support the existence of mid-gap states with Fermi level close to the minimum of the density of states as well as the coexistence of electron and hole carriers. It is suggested that a linear temperature dependence of S with a small negative slope is close to the intrinsic behavior in the a-b plane of normal states for superconducting samples.

基于快速傅里叶变换的地面数字电视广播信号干扰抑制研究

由于信号中杂波的干扰,导致地面数字电视广播信号的误比特率相对较高,因此,提出基于快速傅里叶变换的地面数字电视广播信号干扰抑制。考虑到地面数字电视广播信号本身具有总量大的特点,构建了快速傅里叶变换方式实现对信号的预处理,设置了以时间函数为基础的窗口函数,将其待分析信号相乘,再对得到的乘积结果进行傅里叶变换。对于预处理后的信号,采用分析论证的方式,筛选了两路多级码片扩频调制信号,并按照非线性组合的方式得到无模糊的信号相位检测结果。针对异步信号的特性,实现干扰抑制。测试结果表明,设计方法可以实现对地面数字电视广播信号干扰的有效抑制,在降低信号BER方面具有良好作用。
