In chapter 4, space - time trellis coding ( sttc ) is studied. an exact pairwise error probability is derived for space - time codes operating over rayleigh fading channels
在第四章中，研究了空時格狀編碼的問題，推出了誤碼概率的確切表達式。 -
The advantages of spread spectrum communication are as follows : low probability of intercept, good anti - fading and anti - multipath interference capability. it is widely used in military and civil communication
擴頻通信具有低截獲率、抗衰落能力強、抗多徑干擾等優點，廣泛應用於軍事通信和民用通信。 -
Multibeam base - station smart antennas are discussed in this paper. we analyze the outage probability of mobile communication system suffering both fast fading and shadowing by means of statistical propagation model, and contrast the case that adopt multibeam smart antennas to the case that adopt omnicase. the results emulated by computer show that the outage probability of mobile communication system will diminish as the increasing of the number of beams using smart antennas no matter when suffering a single co - channel interfence or six ones
研究了移動通信環境下的多波束智能天線，並基於統計傳播的同通道干擾模型，分析了快衰落及慢衰落情況下未採用多波束智能天線與採用多波束智能天線時的中斷率，並進行了比較.計算機模擬結果表明：採用多波束智能天線，不論在單個同通道小區還是多個同通道小區情況下，系統的中斷率將隨著波束數的增大而降低 -
Then, base on the determine channel modeling methods, we present a frequency - selective mimo fading channel with von mises probability density function, which is used to characterize non - uniform angle - of - arrival caused by non - isotropic scattering. then we analyze partial cross correlation function of proposed model and proved the model theoretically
然後，通過對其它多入多出通道模型的分析和對比，並基於確定性通道建模方法，建立了一種通用的頻率選擇性多入多出衰落通道模型，藉助「 vonmises 」概率密度函數，以描述非均勻散射體導致的非均勻本地來波方向分佈。 -
The direct sequence spread spectrum ( dsss ) signal has been widely used, owing to the ability of lower working signal - to - noise ratio ( snr ), strong anti - jamming, lower probability interception and mitigating the effects of multi - path fading
直接序列擴頻（ dsss ）信號由於具有工作信噪比低、強抗干擾性、低截獲率、能夠抑制多徑效應等優點，已經得到廣泛應用。
