  3. Abstract : by comparing the channel capacities hetwem orthogonal space - time block coding and multi - antenna array system over rayleigh fading channel, some capacity loss for orthogonal space - time block coding is obtained, which is a function of the code rate, the rank of channel matrix and the number of transmitter and receive antennas, although the system of orthogonal space - time block codes is simple and easy to implemented. if is also shown that there is no capacity loss only if both the code rate and the channel matrix rank are all one

    文摘:在研究瑞利衰落條件下正交空時分組編碼通道容量的基礎上，將其與多發送多接收天線系統的通道容量進行了比較.比較結果表明，正交空時分組碼雖編碼簡單，易於實現，但在通道容量方面存在較大的損失，損失的程度與編碼碼率、通道矩陣的秩及收發天線數等因素有關.進一步研究表明只有當編碼碼率和通道矩陣的秩都為1時，才沒有通道容量的損失
  4. In the spread spectrum communication system, the synchronization of receiver ' s persedo - noise ( pn ) code to the transmitter ' s pn code is such an important part that the whole system ca n ' t work at all without it

The approach in this thesis first design the best performance channel code in different channels and different snr, then design the adaptive coder / decoder. the receiver continually estimates the fading and noise of the channel and transmits them to the transmitter by reverse channel. then the transmitter use these information to choose the best channel code adaptive the current channel

    本文提出的自適應調制方案首先設計各種通道衰落和信噪比條件下的最優通道編碼，再設計一種能夠完成這些通道編碼解碼的自適應編碼解碼器；接收機不斷估計通道的衰落程度和噪聲功率，並通過反向通道反饋給發射機；發射機據此選用最適合當前通道的通道編碼，實現自適應。
