Abstract

While channel coding is a standard method of improving a system s energy efficiency in digital communications, its practice does not extend to high-speed links. Increasing demands in network speeds are placing a large burden on the energy efficiency of high-speed links and render the benefit of channel coding for these systems a timely subject. The low error rates of interest and the presence of residual intersymbol interference (ISI) caused by hardware constrai ....etc

Abstract:

Since 2005, IEE 802.11-based networks have been able to provide a certain level of quality of service (QoS) by the means of service differentiation, due to the IEE 802.11e amendment. However, no mechanism or method has been standardized to accurately evaluate the amount of resources remaining on a given channel. Such an evaluation would, however, be a good asset for bandwidth-constrained applications. In multihop ad hoc networks, such evaluation becomes even more difficult. Conseq ....etc

Abstract

Designing a system able to cope with a hostile channel is a typical challenge for data communication Engineers. High- data- rate communication over power lines is an exemplar case: while power lines are potentially convenient and in expensive no new wire medium for data transmission their features make it very difficult to design a simple modem. This paper illustrates main features of hostile channel, and some of the solution advocated for modem design. ....etc

Analog-Digital Hybrid Modulation for Improved Efficiency over Broadband Wireless Systems


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 advantag ....etc
