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,在时域上給出了闭合表达式。同时选择3种不同原型滤波器,对比分析了其时域结果。结果表明,在浮点运算下,随D逐步增加,Nyq2作为原型滤波器的滤波器组的性能最终会优于Remez和rcosine。
An expression of received signal is presented for multi-carrier system, and the analysis in time do- main is developed. On the basis of the analys, three different kinds of filters （named Rcosine, Remez, Nyq2 in the paper） models are chosen. By presenting and comparing the results of simulations in time do- main, analysis of performance is given. The results show that Nyq2 will have the better performance than other two filters in the GMC system as the size of D increased under the float based calculation.
