英文摘要	We propose in this paper a non-cyclic prefixed multiple-input multiple-output orthogonal frequency division multiplexing (non-cp MIMO-OFDM) system based on a recursive algorithm of joint channel estimation and data detection. Unlike in the traditional cyclic prefixed MIMO-OFDM system, the transmitted sequence of the proposed system is given in the way that block-type pilot sequences and OFDM symbols have been arranged alternately without any cyclic prefix (CP) before each OFDM symbol. Moreover, a recursive algorithm of joint channel estimation and data detection (recursive-JCEDD) based on Interference cancellation is proposed for the corresponding receivers. Simulation results show that the proposed system based on the recursive-JCEDD algorithm achieves lower bit error rate (BER) and higher information data rate than the traditional cyclic prefixed MIMO-OFDM system with least square (LS) or iterative LS channel estimation algorithm.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000263466100131&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Telecommunications; CPCI-S(ISTP); 0
