Fast Internet access is growing from a convenience into a necessity in all aspects of our daily lives. Unfortunately, this has been held back by the high expenses of wiring infrastructure essential to deliver such high-speed internet access especially to private homes, small offices and rural areas, where the installation of any kind of new wires tilts the scales of the economic feasibility to a non-profitable state. This problem is known as the ?last mile problem? which has been an active area of research throughout research community.

This paper seeks to present ways to eliminate the inherent quantization noise component in digital communications, instead of conventionally making it minimal. It deals with a new concept of signaling called the Signal Code Modulation (SCM) Technique. The primary analog signal is represented by: a sample which is quantized and encoded digitally, and an analog component, which is a function of the quantization component of the digital sample. The advantages of such a system are two sided offering advantages of both analog and digital signaling. ....etc

Abstract

Comparative studies on DWT-OFDM and FFTOFDM systems are presented. The model for DWT-OFDM includes zero-padding and vector transpose for transmitting the OFDM signal. MATLAB simulation commands are also described. The discrete wavelet transform-OFDM (DWT-OFDM) has to satisfy the orthonormal bases and the perfect reconstruction properties to be considered as wavelet transform. Different wavelet families have been used and compared with the conventional ....etc

Abstract
IEEE 802.16 standard and WiMAX (Worldwide Interoperability of Microwave Access) will standardize and promote wireless broadband as a wireless alternative to digital subscriber line (DSL) and cable that can help remove barriers to broadband access by providing last mile connectivity. The standard reduces costs, improves security, throughput and makes the connection more exible and scalable. WiMAX operates using a base station and a subscriber station with the base station controlling access within a cell. WiMAX could als ....etc

Abstract

The demand for high-speed mobile wireless communications is rapidly growing.
OFDM technology promises to be a key technique for achieving the high data capacity and spectral efficiency requirements for wireless communication systems of the near future. This work presents an investigation into methods for maximizing the spectral efficiency of Orthogonal Frequency Division Multiplexing (OFDM) systems. The current standards such as IEEE 802.11a in USA and ....etc

The Technology Broadband over power line (BPL) is another high speed data service available to consumers. It uses medium and low voltage power lines to carry broadband data at speeds between 500 Kbps and 3 Mbps. At these data rates BPL is equivalent to and competes with cable and DSL. Access BPL and In-home BPL are both used to deliver data to the consumer over power lines. Access BPL is used to carry data over the medium voltage and low voltage power lines to the customer?s premises. Power companies also use Access BPL to monitor power grids. ....etc
