   ( 3 )討論了非可逆線性內(nèi)動機在正規(guī)空間、直交空間、正交空間上的圖型結(jié)構(gòu)問題[定理3 . 10 3 . 13 ] 。
5. 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信道容量的基礎(chǔ)上，將其與多發(fā)送多接收天線系統(tǒng)的信道容量進行了比較.比較結(jié)果表明，正交空時分組碼雖編碼簡單，易于實現(xiàn)，但在信道容量方面存在較大的損失，損失的程度與編碼碼率、信道矩陣的秩及收發(fā)天線數(shù)等因素有關(guān).進一步研究表明只有當(dāng)編碼碼率和信道矩陣的秩都為1時，才沒有信道容量的損失
