【正文】 。MQAM的符號流經(jīng)過串并轉(zhuǎn)換之后每n個符號組成一個相量，是和傳統(tǒng)正交頻分多路復用一樣是用來調(diào)制子載波的，但是不同的是只有這n個活躍子載波進行了調(diào)制。致謝致謝本論文的工作是在我的導師XX老師悉心指導下完成的，……外文資料譯文外文資料原文A Tight Upper Bound on Bit Error Rate of Joint OFDM and MultiCarrier Index Keying II. Joint MCIKOFDM System ModelWe consider a peertopeer MQAM OFDM transmission with Nc subcarriers that consists of n clusters of N sub—carriers(i. eNc=nN). A stream of MQAM symbols is first serialtoparallel converted, where every n()symbols are grouped into a vector and are used to modulate subcarriers, as in the classical OFDM, but it differs from that the modulated subcarriers are only those of n activated indices, similar to [4], [5].……外文資料原文1000字左右，英文標題，段落—段前30磅，段后30磅；行間距固定值20磅，首行縮進2字符。參考文獻參考文獻[1] 啜鋼, 王文博, 常永宇等. 移動通信原理與應用[M]. 北京: 北京郵電大學出版社, [2] 佟學儉, 羅濤等.
