  4. Researches on the space - time code have been under the assumption of independent fading and perfect channel state information. but in a realistic system, the above assumption is very difficult to be acquired. based on this, the performance of space - time code under correlated rayleigh fading channel and rician fading channel is studied in thispaper

    在實際的傳播環境中，不同天線上的信號的衰落在空間上存在相關性，研究了瑞利相關衰落通道的空間相關性對空時編碼性能的影響以及相關萊斯衰落通道下空時編碼系統的性能，以期推動空時編碼在無線通信系統中的實際應用。
  5. Based on these advantages we analyze the performance of constant - power variable - rate m - qam schemes for spectrally efficient data transmission over nmf channels. by introducing the adaptive modulation approach, we gain two things : 1 ) the error rate is kept at a constant level. 2 ) the achievable spectral efficiency comes within 5 db of the shannon capacity limit. at the last chapter, the presentation of a single base station and a single mobile scenario proved the feasibility of adaptive schemes

    然後作者的精力轉入通道的自適應方案的研究中，首先通過研究發現nakagami衰落因子的適當調整可以近似於常見的瑞利衰落和萊斯衰落，接著研究在無線通道中採用三種不同自適應方案時的通道容量，研究表明速率的調整是增加通道容量的關鍵，在此基礎上，著重研究了離散變速率qam的情況，表明這種調制方案無論在頻帶利用率還是在系統平均誤碼率比其它情況提高很多。
  6. Based on the two ex isting underwater acoustic channel models ( the rice model and the rayleigh model ), we simulated the effects on the image signal underwater transmission with different ofdm parameters. by selecting appropriate ofdm parameters, we realize a simple offline communication system. besides, parts of programs based on ti tms320c62x are realized in this thesis
