英文摘要	This letter proposes a novel factor graph equalization based on a serial layered scheduling (SLS) algorithm of belief propagation, where the channel convolutional matrix is decomposed according to the distribution of its non-zero elements. In the SLS algorithm based factor graph equalization, factor nodes are classified into multiple layers referring to the decomposition of channel convolutional matrix, and the a posteriori probabilities message is updated based on a serial layer-by-layer mechanism. This proposed SLS algorithm clearly decreases the signal-to-noise ratio (SNR) threshold and also increases the convergence speed of equalization process, which results in a higher reliability and a lower latency of equalization process. Compared with current parallel flooding scheduling (PFS) algorithm, the convergence speed of SLS algorithm increases almost by twice, and its SNR threshold reduces by 7 dB over the Proakis-C channel.; http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:000340115200007&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701 ; Telecommunications; SCI(E); EI; 0; ARTICLE; leiym@pku.edu.cn; 6; 925-928; 18
