| Summary: | Exponential increase in demands of wireless access over the years has led to rapid evolution for next generation wireless access technology. However, with scarce spectrum resource yet increasing bandwidth demand has become the main concern since this problem will hinder the evolution process and generally affects network performance. In this paper, by taking 3GPP (3rd Generation Partnership Project) LTE-Advanced (Long Term Evolution - Advanced) as a perfect specimen for 4G (fourth generation) standard candidate, we thoroughly investigate its key technologies thus providing overviews on network performance and efficiency improvement by implementing cooperative communication and cognitive radio (CR) technology. |
