【摘要】 在广义多载波系统下,该文研究了存在子载波间干扰和符号间干扰的接收信号,在频域上给出了闭合表达式。同时选择3种不同原型滤波器,对比分析了其频域结果。结果表明,GMC调制解调滤波器组压制干扰的性能会受到滤波器延时和原型滤波器类型的限制。更多还原

【Abstract】 This paper presents die expression of received signal in generalized multi-carrier(GMC) systems taking into consideration of the modulation/demodulation filter bank,and then the interference analysis is provided in the frequency domain to obtain the close-form interference expression.Moreover,three different kinds of prototype filters,named Rcosine,Remez,Nyq2 in study,are simulated to show the influence of filter type on the interference of GMC systems.The numerical result tells us that the interference performance is limited by the filter delay and the filter type.更多还原
