Digital Communications for Broadband Networks

Introduction ( the revolution ypsirrythmon optical communications and mobile The types of access networks for broadband services) . Overview of traditional forms of digital modulation (ASK PSK, FSK modulation performance using Miadikon shapes , the scope for mixed digital systems , constellations , distance symbol constellation ) . Miadika Digital Modulation Systems with Orthogonal Carriers ( modulation QAM, DMT systems using DMT systems in wired telephone networks , the technique of XDSL use of DMT systems in wireless networks , the technique of OFDM).Combination Coding and Modulation ( precoding , trellis charts and algorithm Viterbi, coding for channels with limited bandwidth , technical TCM). Systems spread spectrum ( model systems , direct sequence system , frequency hopping system , some CDMA applications , low forasimotitas signals , address jamming, addressing multipath).Technical Signal Processing for Communications Broadband (identification and channel equalizers , forecast large-scale signals intermittently , algorithms for bandwidth limitation ) Modems for TV cable (noise and problems in the transmission of discrete data , multiple access techniques , formal methods for the implementation of cable modem). Wireless Communications Broadband (LMDS, MMDS, WAP, GPRS).
