Implementation of Reconfigurable High Speed Architecture for Long Term Evolution Systems

Abstract

Every transition in the generation demands drastic improvement in the technologies that are supporting the transition. Growing interest of users in the wireless industry forced the researchers and academicians to evolve the wireless industry at a faster rate. To meet the increasing demands of the users, new technologies and methods have been introduced. The recent wireless generation in the market is 4G. To meet the ever-increasing demand for data transmission in wireless communication systems, the Long Term Evolution (LTE) standards have been developed as the successor to the Third Generation Partnership Project (3GPP).LTE provides peak data rate of 200Mbps for uplink and 1Gbps for downlink with better coverage. LTE, a 4th generation (4G) mobile standard, is designed and deployed to fulfill the demand and necessity of mobile network expansions across the globe. LTE is provisioned to work on packet switching technique to support web services, media connections, social networking, mobile TV and data streaming services. It uses Orthogonal Frequency Division Multiplexing (OFDM) as an access technique for downlink communication due to its high spectral efficiency. The major bottlenecks to the OFDM performance are Inter Carrier Interference (ICI) and high value of Peak to Average Power Ratio (PAPR). High PAPR in OFDM is attributed to the fact that power distribution among subcarriers is quite non-uniform which results in uneven energy consumption among them. Therefore, any feature enhancement in OFDM through PAPR reduction would contribute in performance improvements of LTE system newline
