The Matlab scripts for Giovanni's DFE work (along with some illustrative screenshots) are now downloadable at the following URL: http://si-list.org/files/DFE/ -Ray -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx] On Behalf Of Guasti Giovanni Sent: Monday, June 06, 2005 2:29 AM To: 'si-list@xxxxxxxxxxxxx' Subject: [SI-LIST] DFE Dear SI-Group members, I would like to exchange some ideas with other people managing=20 problems like mine. I recently wrote a script in Matlab, that helps me to program the=20 equalyzer and the DFE block in a Virtex 4 Rocketio receiver. I would like to choose the right gains (Ci) in order to optimize the=20 eye amplitude and minimize the jitter. I can start from a simulation or from a measure of the signal in front=20 of the receiver. I red the Xilinx UG076 note and I tried to obtain with=20 Matlab something similar to what is described in pages 109-112. But I =20 still have some doubt (phases of equalyzers, how really the DFE works....) So I would like to share my code and find someone who could help me=20 with some suggestions. I hope that SI-List is the right place. Thankyou Giovanni You should be able to downolad the scripts from www.si-list.org soon (Thankyou Ray) ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl?Si-List_FAQ List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
