Recently, multiple input multiple output ( mimo ) system which originates from the employment of multiple antennas at transmitter and receiver has many advantages such as large system capacity, high spectral efficiency . on the other hand, orthogonal frequency division multiplexing ( ofdm ) which bases on the orthogonal transmission of sub-carriers also has some obvious merits such as strong anti-multipath ability, high spectral efficiency . the combination of the two techniques mimo-ofdm, has become a hotspot recently and regarded as promising technique for future next-generation mobile communication systems 近來,在無線通信系統(tǒng)中的收發(fā)兩端同時(shí)使用多根天線的多入多出(mimo,multiple-input-multiple-output)通信結(jié)構(gòu),具有系統(tǒng)容量大、頻譜效率高等優(yōu)點(diǎn);基于正交的多路子載波并行傳輸?shù)恼活l分復(fù)用(ofdm,orthogonalfrequencydivisionmultiplexing)技術(shù),具有抗多徑能力強(qiáng)、頻譜效率高等優(yōu)點(diǎn),二者的結(jié)合,即mimo-ofdm技術(shù),被認(rèn)為是構(gòu)建下一代移動(dòng)通信系統(tǒng)的框架技術(shù)。
Iterative processing technique which is a nonlinear technique for joint signal processing by the means of exchanging prior information can approach better performance than traditional receiver, so this thesis introduces the research of iterative detection in anti-jamming communication system and distributed multiple input multiple output system 迭代檢測(cè)技術(shù)通過交換信號(hào)先驗(yàn)信息,將原本獨(dú)立的信號(hào)處理模塊聯(lián)系起來,使系統(tǒng)獲得更優(yōu)越的性能。因此,本文圍繞著迭代檢測(cè)技術(shù)在抗干擾系統(tǒng)和分布式多輸入多輸出系統(tǒng)中的應(yīng)用進(jìn)行了研究。
