Asymmetric Digital Subscriber Line

might wonder how all of these millions of people are connecting to the Internet. There are many different options for people to use to connect to the Internet, such as dial-up, DSL, Cable, and Satellite. Dial-up internet connection uses the telephone line; this is the oldest connection that has been around since the 1990’s. The newest type of connection would be the satellite connection, which is not very popular right now because of the high cost. The two most popular

T carriers, e.g., T1 and T3, are digital, leased twisted-pair lines, designed to carry voice (via Pulse Code Modulation (PCM)) and data communications up to distances of 48miles/80km. Approximate available bandwidth for a T1 is 1.5Mbps, and for a T3, 45Mbps of available bandwidth. T1s provide 24 64Kbps channels and a T3, made up of 28 T1s, can provide 672

a dial rather than numbers on an LCD screen. In an analogue telephone system, the audio signal is converted into electronic pulses. This creates vibrations in the handset’s speaker that can be picked up by the person listening. Nevertheless, in a digital telephone. The audio signal is converted into binary format. The binary format consists of groups of 0’s and 1’s. The audio signal is ‘sampled’ thousands of times a second and

The DSL modem of each customer uses the existing telephone line so that it can exchange data with digital subscriber line access multiplexer(DSLAM) which is located at the local central office of Telco. The DSL modem of home takes the digital data and translates it to high- frequency tones for transmission over telephone wires to the CO. At the DSLAM many analog signals are translated back into digital format. The residential telephone line carries both data and traditional signals at the same time

1.1 INTRODUCTION The aim of third and fourth generation (3G/4G) mobile networks is to provide users with high data rates, and to provide a wider range of services, such as voice communications, videophones, and high speed Internet access. A common challenge in a wireless system design is to overcome the eects of the wireless channel, which have multiple transmission paths and dierent delays. OFDM has a promising future as a new technology in several next generation wireless communication systems
