3 . the graph structure of some non - invertible autonomous automata is discussed in regular space , orthogonal space , and orthonormal space respectively . some new results are derived [ theorem 3 . 10 - 3 . 13 ] ( 3 )討論了非可逆線性內(nèi)動(dòng)機(jī)在正規(guī)空間、直交空間、正交空間上的圖型結(jié)構(gòu)問(wèn)題[定理3 . 10 3 . 13 ] 。
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(shí)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(jìn)行了比較.比較結(jié)果表明,正交空時(shí)分組碼雖編碼簡(jiǎn)單,易于實(shí)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(jìn)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(shí),才沒(méi)有信道容量的損失
