	MAC protocol with dynamic priority adjustment for light trail networks (EI CONFERENCE) 会议论文 OAI收割 Network Architectures, Management, and Applications VIII, December 8, 2010 - December 12, 2010, Shanghai, China 作者: Fang W.; Li S. 收藏 \| 浏览/下载：55/0 \| 提交时间：2013/03/25 In order to improve the wavelength utilization as well as the fairness of the light trail networks we modified the FP MAC from the view point of weight balance by introducing a weight mode. The weight mode is composed of two factors real-time factor and node activity ratio. Moreover the weight mode is used as a bid by each LT node to compute the priority. Hence the priority of the LT node is adjusted dynamically in every round and the MAC protocol with dynamic priority adjustment is entitled as DPA MAC. Simulation results show that the performances of DPA MAC protocol are much better than that of FP MAC protocol in terms of packet loss rate and activity percentile. 2011 Copyright SPIE - The International Society for Optical Engineering.
	OFDM baseband modulation technology based on VHDL (EI CONFERENCE) 会议论文 OAI收割 2010 IEEE International Conference on Advanced Computer Control, ICACC 2010, March 27, 2010 - March 29, 2010, 445 Hoes Lane - P.O.Box 1331, Piscataway, NJ 08855-1331, United States Lin L.; Qiao Y.-F.; Su W.-X. 收藏 \| 浏览/下载：32/0 \| 提交时间：2013/03/25 In order to improve the transmission velocity in mulitipath fading wireless channel two main advantages are obtained via discussing spectrum utilization ratio of OFDM. Then the high speed OFDM technology receives increasing attentions in mobile communication. Modulation programs are designed with VHDL based on the principle of OFDM in the paper. First from the results of VHDL simulation after OFDM fundamental is introduced the realization of baseband operations such as interleaver subcarrier modulation IFFT and adding CP are presented. Finally implemented programs are validated on the actual implement system. Experimental results indicate that setup time corresponding to transmission velocity is only 71.05s and steady time is approximately 6 times as setup time that is not only achieving the high speed transmission but also supplying adequate modulation time. 2010 IEEE.
