Abstract
Digital transmission makes out the major part of the digital communication networks. The core of the communication networks is based on digital carriers. Local area networks exchange their information on digital carriers called Ethernet. Digital transmission has many advantages versus analog transmission. In order to make full use of these advantages one has to overcome the distortion of the signal and the transmission line. This is achieved by the equalizers. Unfortunately, the signal is contaminated by thermal noise. These noise signals can be partly removed by the matched filter. Matched filter is basic tool in electrical engineering for extracting signal that has been contaminated by noise. The filter will maximize the signal to noise ratio (SNR) of the signal being detected with respect to the noise. Ethernet is the most common type of connection between computers in a local area network (LAN). The original Ethernet was created in 1976 at Xerox’s Palo Alto Research Center (PARC). It has gone through four generations (standard Ethernet (traditional), fast Ethernet, 1Gbps Ethernet and 10Gbps). Ethernet technologies are still in constant evolution since its inception in 1976, thus increasing the ability to expand and accommodate the largest possible number of devices that are connected with the possibility of securing transport at high speeds during small times.
Fast Ethernet began to be widely deployed in the mid-1990s. Fast Ethernet supports a maximum data rate of 100 Mbps. It is named because original Ethernet technology supported only 10 Mbps. Ethernet networks use a variety of cable types (such as fiber optics). Gigabit Ethernet is the version of Ethernet. Gigabit Ethernet offers higher performance 1000Mbps (1Gpbs) that is one hundred times faster than the original Ethernet.
The aim of this thesis is to develop a MATLAB model of matched filter for fast Ethernet (100baseFx) and Gigabit Ethernet system and present detailed matlab models, simulation results, and bit error rate comparisons.
