Physical layer features of Ethernet from the first realization towards the 100 Gb Ethernet (100 GbE) development have been considered. Comparisons of these features are made according to the standardized data rates. Feasible physical layer options are then discussed for high data rates.
This paper and the following presentation aim to provide a report regarding the seminar presentation given on 23.02.2011 as a part of the postgraduate seminar course S-88.4223 Wavelets in Communications lectured by Dr. Sumesh Parameswaran at Aalto University School of Electrical Engineering. In particular, the topic on "wavelets for single carrier communications" has been considered herein. Furthermore, a summary of wavelets in Single Carrier (SC)-FDMA Systems is as well provided.
Relaying is a promising enhancement to current radio technologies, which has been considered in IMT-Advanced candidate technologies such as 3GPP LTE-Advanced and IEEE 802.16m. Relay enhanced networks are expected to fulfill the demanding coverage and capacity requirements in a cost efficient way. Among various relaying architectures multi-hop moving relays can provide additional capacity for the cases when fixed relays are inaccessible or not able to provide adequate solutions in terms of cost. In this paper, an overview of multi-hop moving relays along with some of the envisioned deployment scenarios is presented. Furthermore, different types of multi-hop moving relays are discussed and the challenges are addressed.
Relaying is considered a promising cost-efficient solution in 3GPP LTE-Advanced for coverage extension and throughput enhancement. The compact physical characteristics and low power requirements of the relay nodes offer more flexible deployment options than traditional macro evolved Node Bs. This paper provides an overview of general relaying concepts and presents the relay deployment within the LTE-Advanced framework. Furthermore, the impact of relay backhauling on envisioned relaying gains is discussed and the methods to improve the performance of the backhauling are included.
