100-Gb/s and beyond transceiver technologies
Optical Fiber Technology, 2011Co-Authors: Christopher R. ColeAbstract:Abstract First generation 100-Gb/s Ethernet transceiver architecture, standards and components are presented. Second generation 100-Gb/s architecture, standards and enabling photonic integration component technology are then described. Extension of this technology is shown to support cost effective 400-Gb/s Ethernet interfaces. The next OTN Data Rate then also becomes 400-Gb/s to efficiently carry a 400-Gb/s Ethernet payload. Further Data Rate Increase to ⩾1-Tb/s is not possible with existing technology, and will require completely new technology R&D effort.

55 Data Rate Increase of sstl dram interface channels by eliminating crosstalk induced jitter
대한전자공학회 학술대회, 2009Co-Authors: Haekang Jung, Hye Jung Kwon, Hongjune ParkAbstract:The maximum Data Rate of a 2-drop SSTL DRAM interface channel was Increased by about 55% by eliminating the crosstalk-induced jitter due to the microstrip line and the DIMM connector. The maximum Data Rate was defined to be the Data Rate at which the eye opening of the received signal contains the rectangle with the voltage opening of one-fourth the received DC swing and the time opening of two-thirds the Data period. A serpentine shaped structure was used in the microstrip line on the PCB to eliminate the far-end crosstalk by increasing the capacitive coupling ratio up to the inductive coupling ratio. Also the mutual capacitance components are added in the 184-pin DIMM connector to eliminate the far-end crosstalk due to the DIMM connector. Two parallel coupled lines with the length of 8 inches and the same spacing are used in both the conventional and proposed works. Compared to the conventional channel, the proposed work Increased the maximum Data Rate by about 55% from 0.9 Gbps to 1.4 Gbps for the input pin capacitance of DRAM chip of 3.5 pF.

Ultra-long haul WDM transmission at Data Rates exceeding 10 Gb/s
Optical Fiber Communication Conference and Exhibit, 2002Co-Authors: Morten Nissov, C. R. DavidsonAbstract:High-Data-Rate transmission at 20 Gb/s has been demonstRated over both Trans-Atlantic and Trans-Pacific distances. To make 40 Gb/s systems economically viable it is important to achieve the Data Rate Increase without significantly increasing complexity. This ensures that the inherent advantages of high-bit-Rate transmission are realized: reduced cost, power consumption, and floor space.

Adaptive Modulation and Coding Rate for OFDM Systems
Ijetae.Com, 2013Co-Authors: Ts Harivikram, R. HarikumarAbstract:Wireless communication is observing a fast development in today’s communication era. A poorly designed path can result in periodic system outages, resulting in Increased system latency, decreased throughput, or worst case, a complete failure of the system. Planning a good, stable and reliable network can be quite challenging. At the same time, it poses several interesting optimization problems. Today wireless technology is used in many applications well integRated into our everyday life. The basic motto of communication system is to ensure the exchange of information in between the people. When this communications without wired then it’s referred to wireless communications. Now-a-days, this wireless communications gets more attention from the Communication industry and provide better quality information transfer between portable devices. After the implementation of 3G network, numerous applications like Autonomous sensor networks, Multimedia, Videoconferencing, and Distance learning and Internet enabled cell phone are developed. Also Long Term Evolution (LTE) is going to evolve to Increase the Data Rate, Increase throughput, decrease latency, etc, for the above applications and also to bring lot of applications. Our primary design objective in this paper is to minimize the error probability of a LTE system and to bring the spectrum efficiency through a process known as adaptive modulation and coding Rate. LTE normally uses OFDM as its technology and we are going to implement the adaptive modulation in OFDM systems
