Ofdm system is a very promising technology since it has many advantages , such as its high - efficient spectrum and ici interference avoidance . it can also easily connect with mimo and access technologies like fdma , tdma , and cdma . because different subcarriers can adopt different coding and modulation methods , the capacity of the channel is able to reach the optimum value Ofdm多載波調制解調系統,具有抗多徑干擾能力強,頻譜利用率高,可以與mimo技術、不同的多址接入方式相結合,可使信道容量到達最優,所以基于ofdm的多載波調制解調系統越來越得到廣泛的應用。

In this chapter , cck codeword has been described . following this are the algorithm of cck receiver scheme , includeing maximum likelihood receiver under awgn channel - rake and rake - isi receiver based on the channel matched filter and decision feedback equalizer . chapter 5 is a report about the receivers performance simulations 在這一章中對cck調制及碼字的特點進行詳細描述,隨后詳細闡述我們所采用的幾種cck接收機方案中的算法,包括加性噪聲信道下的最大似然接收機、基于信道匹配濾波器的rake接收機、帶isi刪除的rake接收機(即rake - isi ) 、帶isi和ici刪除的rake接收機(即rake - isi ici )以及判決反饋均衡器。

At present , the fund industry steps into the prosperous stage , and ici said that in 2004 there is a net inflow of $ 49 . 78 billion into the mutual fund market , and capital funds amounted to $ 7 . 54 trillion . the amount of capital funds in the world is more than $ 10 trillion 目前全球證券市場基金業蓬勃發展,生機盎然,據美國投資公司協會( ici )表示, 2004年美國共同基金市場凈流入497 . 8億美元,使得基金整體資產增加至7 . 54萬億美元,目前全球基金規模超過10萬億美元。

A group of orthogonal frequency carriers are used in ofdm system to improve the using rate of spectrum . if the orthogonal character can be held and ignore the inter - channel interference ( ici ) , the symbol error character of ofdm depend on the modulate of source codes . this dissertation propose the theoretic formula of ofdm - qam and ofdm - psk in this precondition 為了提高頻譜利用率, ofdm系統使用了一組正交的子載波來傳輸信號,若能保證各子載波間的正交性不被破壞、不考慮信道間干擾( ici ) ,則ofdm系統的誤碼性能由信元調制方案的誤碼性能決定,文中推導了該情況下ofdm - qam和ofdm - psk的理論誤碼率公式。

Firstly , in wireless environment , receiver has no know the time delay between transmitter and itself . in ofdm system , ofdm data is transmitted as one symbol , so in order for correct demodulation , the correct start of symbol should be got from ofdm system to reduce the effect of isi . secondly , the high frequency utilization in ofdm is based on the orthogonal properties of sub carriers . if frequency offset is generated , the orthogonal properties among sub carriers will lost , that will cause inter carrier interference ( ici ) and high ber of system Ofdm技術也存在著一些缺陷,首先,在無線環境中傳輸的ofdm信號對定時要求高,為了減少碼間串擾( isi )影響,必須從接收信號中提取出正確的符號起始位;其次, ofdm系統對頻率偏移敏感, ofdm技術的高頻譜利用率和傳輸可靠性均以子載波的正交性為基礎,如果接收機和發射機之間發生頻率偏移,子載波之間就會失去正交性,導致嚴重的子載波間干擾( ici ) ,降低系統性能。

So the embassy here will spend a lot of time talking and working very closely with those major companies like bp , shell or ici , helping them to do business in china by giving them political support , by interpreting what is happening within your country , by helping them through the difficulties to set up a joint venture 因此這里的大使館會花大量的時間與那些大型公司,如英國石油、殼牌或卜內門,密切地交流和工作,為幫助他們在中國做生意向他們提供政治上的支持,向他們說明你們國家的狀況,幫助他們克服設立合資企業所遇到的困難。

For example , carrier frequency offsets , which are caused by the inherent instabilities of the transmitter and receiver carrier frequency oscillators , can lead to severe system degradation due to inter - carrier interference ( ici ) . symbol timing synchronization must also be achieved in order to avoid inter - symbol interference ( isi ) 其載波頻率誤差會引入子信道之間的干擾( ici ) ,而幀同步的誤差會引入符號間干擾( isi ) ,同時還會對信道估計帶來嚴重的影響。

To overcome the affection of ici and awgn on the ls estimate of the transfer function at pilot tones , the proposed bispectrum - based channel estimation algorithm employ the suppression of ici and awgn components in the received pilot signals by bispectrum and then the accuracy of the estimation is improved . with the channel estimation at pilot tones , an efficient interpolation is necessary . an improved interpolation method based on transform - domain filtering is proposed , which employs dft / idft and filtering in a transform domain so that the effect of noise on the equalization is significantly reduced 針對導頻處信道傳遞函數的ls估計中存在載波間干擾和加性高斯白噪聲的影響的這一問題,本文將傳統的ls估計方法與雙譜相結合提出了一種新型的基于導頻雙譜信道估計算法,它利用了雙譜對高斯噪聲的抑制作用來減小接收到的導頻信號中的載波間干擾和加性高斯白噪聲的影響,從而提高了導頻子載波上信道估計的精度。

In the end , this paper considered detecting the desired user signal for uplink ds / cdma system . in that case , we need to suppress both mai and inter - chip interference ( ici ) caused by multipath propagation 最后,本文研究了在ds cdma的上行信道中,同時存在多用戶干擾和多徑傳播引起的碼間干擾的情況下,對期望用戶信號的檢測。
