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Our various products included : series38 50 open window spring door, series 46 spring door, series 64 70 73 75 76 80 81 82 90 112 push - pull window and series 360 degree versatile multi - function patent push - pull window, series 110 120 130 semi - hidden frame glass screen and wall profiles, over 100 series especial industrial profiles, eg : ceilings, cabinet, curly door, and bathroom and other ornate materials etc. over 2000 specification powder spraying and eletrophoretic coating profiles, products color series such as : based bronze, silver white, lusterless etc
