Although many researchers have written about OFDMA transmission system, it needs more attention and analysis in next generation wireless networks. This paper is aimed at studying the performance analysis of OFDMA in WiMAX IEEE 802.16m and 3GPP LTE Advanced systems Communication in hybrid environment systems. This study further focuses on Downlink and Uplink models. Finally, it summarizes simulation...
In this paper, factors that impact urban ecological environment such as pavement performance, physical environment and economical index have been synthetically estimated by the method of multi-level fuzzy pattern recognition, It turned out to be that physical environment is very good with 34% and ecological environment is good with 31%, this proved that porous pavement can improve urban ecological...
