Fast Application Programming Interfacebetter known as FAPI is a standard in which exchangeof information between the two layers is performs viacertain message structures. 4G systems of today such asLong Term Evolution (LTE)can make use of this FAPIstandards in order to exchangeconfiguration betweenthe different Layers as well as providing indications anderrors. This paper focuses on introducinganAdvancement...
The purpose of Cyclic Prefix (CP) is vital necessity in today's 4G technology. 4G Technology such as Long Tern Evolution (LTE) and Worldwide Interoperability for Microwave Access (WIMAX) function on the principle of Orthogonal Frequency Division Multiplexing (OFDM). When transmitted signals arrive at the receiver by more than one path of different length, the received signals are staggered in time;...
Physical Uplink Control Channel (PUCCH) is a transmission channel used to transport acknowledgment responses and retransmission requests (Hybrid Automatic Repeat Request (HARQ ACK/NACK)) for Downlink (DL) data packets, send service scheduling requests (SR), transfer channel quality information (CQI) and Multiple Input Multiple Output (MIMO) feedback (such as Rank Indicator (RI) or Precoding Matrix...
Channel quality indication (CQI) reports are vital element of Long Term Evolution (LTE) system in providing information on the downlink channel quality. The 3GPP standard mentions the encoding method for CQI is Reed Muller (RM) code and the transmission quality of CQI can be improved by channel coding with RM code. The paper presents a SNR dependent CQI Decoding mechanism over an existing method which...
With the increasing requirement of higher data rates to support various multimedia applications, a demand for an enhanced wireless communication system has become a necessity. During the development-stage of any such wireless communication system it is necessary to perform continuous functional and performance tests for a reliable and efficient end-product. It is also necessary to develop a cost effective...
In 4G wireless communication technologies such as LTE/LTE-A, signal to interference plus noise ratio (SINR) measurement is one of the major requirements for optimum link performance. The SINR measurement importance spans into various applications, for example: optimization of transmit power level, better named as close loop power control (CLPC), assisting with handoff decisions and dynamically adapting...
