GB 09G 09H 33544 ESPRIT XE CEZ:AV0Z1075907 It has been shown that a 32-bit logaritmic arithmetic unit can operate faster than, and maintain the accurancy of, a 32-bit floating point unit. It uses the logarithmic number system (LNS), in which a real number is represented as a fixed-point logarithm. In this paper we investigate the implementation of three fast affine projection (FAP) algorithms using LNS. We propose a simplified Conjugate Gradient FAP (SCGFAP) of the CGFAP and the SCGFAP algorithm are superior to those of the classical FAP algorithm. cav_un_auth*0212962 Irish Signals and Systems Conference 2002 Cork IE 25.06.2002-26.06.2002 JC ZS http://hdl.handle.net/11104/0131004 UTIA-B 20020131 2002 2002 Cork Institute of Technology 0-9542973-0-X Proceedings of the Irish Signals and Systems Conference 2002.
