A Tight Upper Bound on Bit Error Rate of Joint OFDM and
Multi-Carrier Index Keying
II. Joint MCIK-OFDM System Model
We consider a peer-to-peer M-QAM OFDM transmission with Nc sub-carriers that consists of n clusters of N sub—carriers(i. eNc=nN). A stream of M-QAM symbols is first serial-to-parallel converted, where every n(?Nc)symbols are grouped into a vector s?[s1,s2,......sn]T and si?S are used to modulate sub-carriers, as in the classical OFDM, but it differs from that the modulated sub-carriers are only those of n activated indices, similar to [4], [5].

基于多载波索引键控的正交多路复用系统的误码率上界 二．基于多载波索引键控的正交频分多路复用系统模型
我们考虑一个端到端的M-QAM，Nc子载波的基于多载波索引键控的正交频分多路复用系统有n个簇，每个簇有N个子载波（Nc=nN）。M-QAM的符号流经过串
Ts?[s1,s2,......sn]si?S是和传统正交频分多并转换之后每n个符号组成一个相量，路复用一样是用来调制子载波的，但是不同的是只有这n个活跃子载波进行了调制。??
