IMPLEMENTATION OF ENHANCED NA GAUNN TECHNIQUE (ENGT) FOR RESOURCE BLOCK ALLOCATION IN LTE SYSTEMS FOR IMPROVING THROUGHPUT

Abstract

The study shows that distinct and unique features viz. high speed data rate, self-organized network, packet optimized radio access; low latency and flexible bandwidth deployment are the parameters that enable LTE (Long Term Evolution) to be preferred in wireless communication systems. This terminology is preferred especially for mobile nodes that help to improve speed that ultimately increases throughput. As LTE (Long Term Evolution) uses Orthogonal Frequency Division Multiplexing (OFDM) for the downlink data transmission that means for sending data over narrow band barriers 5MHz career bandwidth is used. The complete working of LTE is based on the basic principle of OFDM (Orthogonal Frequency Division Multiplexing). At the first step, it divides the broad spectrum into multiple narrow bands and transmits information on this narrow channel in parallel.OFDM meets the LTE requirement for spectrum flexibility and enables cost-efficient solutions for very wide carriers with high peak rates. Orthogonal frequency-division multiplexing (OFDM), is a frequency-division multiplexing (FDM) scheme used as a digital multi-carrier modulation method for implementing scheduling. In general, scheduling plays a vital role on the time of resource allocation and that only can be based on the need as well as priority of the user. The main three parameters considerations are viz. resource block scheduling, power control and client association taken by the authors.The mainmotive to design and implement this new designed methodology is the right utilization of resources at a right time when users send request to the system that either may send on the same time or send on the different-2 time slots. By implementing this ENGT (Enhanced Na Gaunn Technique) speed of LTE systems can be easily improved that automatically helps to improve the throughput of the system. In this paper, there are 4 different types of modulation coding schemes (MCS)are applied as like QPSK, QAM,16QAM and 256 QAM etc. The main focus of authors is while implementing ENGT (Enhanced Na Gaunn technique) improves the throughput of the system. By implementing this, resources are properly distributed in resource blocks at specific data rate requirement and allocated resource rate & rightly utilized at right time. The main benefit to implement this ENGT isto handle user requests efficiently while performing right distribution of resources at right time. Hence, authors said this enhanced version of Na Gaunn algorithm may help to fulfill requests optimally and especially on time without any delay after sending the request to the computer system. In this way, the throughput of the system can be easily improved by implementing Enhanced Na Gaunn Technique and automatically the channel quality indicator and performance would automatically be improved.
