The relationship between performance and the number of sub-carriers in MC-CDMA system is analyzed in theory, with criterion of sub-carriers SJR in receiver.
以接收端子载波上接收到信号的信干比为评价标准,从理论上分析了系统性能与子载波数目N的关系,认为子载波数目N在满足每个子信道均为非频率选择性衰落信道后,进一步增大不会带来系统性能的改善,反而会带来运算量增大,峰平功率比提高等问题;当信干比很大时,系统性能甚至会随子载波数目N的增加而恶化。
