Abstract:
Long Term Evolution (LTE) is the latest standard in the cellular
communication. It is a standard developed by the Third Generation Partnership
Project (3GPP). 3GGP is referred as a joint standardization partnership that
responsible for standardizing Universal Mobile Telecommunications System
(UMTS), High-Speed Packet Access (HSPA) and LTE standard. The main
objectives of LTE are to provide a high-data-rate, low-latency and packet-optimized
radio access technology supporting flexible bandwidth deployments. In conjunction
with the latest standard, a new network architecture is developed with the aim to
support packet-switched traffic with seamless mobility, quality of service and
minimal latency. The new network architecture compromises a single platform
network. The research paper provides an overview of the LTE physical layer (PHY),
including technologies that are newly deployed to cellular such as Orthogonal
Frequency Division Multiple Access (OFDMA) in the downlink transmission and
Multiple Input Multiple Output (MIMO) antenna system. The latest MIMO antenna
system includes the schemes of Transmit Diversity (TD), Open Loop Spatial
Multiplexing (OLSM) and Closed Loop Spatial Multiplexing (CLSM). The research
paper focuses on the comparison performance of different number of Quality
Channel Indicator (CQI) used during the downlink transmission and the comparison
performance between different types of MIMO schemes.Long Term Evolution (LTE) is the latest standard in the cellular
