چکیده
To meet the overwhelming demand for high data rate mobile applications, 3GPP long-term evolution (LTE) is quickly developing around the world as a major step forward in cellular technology. In December 2009, the world’s first commercial LTE service opened by TeliaSonera in Stockholm and Oslo. In September 2010, the first US commercial LTE service launched by MetroPCS in Las Vegas and Dallas. On December 5, 2010, Verizon Wireless launched its 4G Band13 LTE network in 38 markets covering 110 million people in the United States and targeting full nationwide coverage in 2013.

Clipping Based PAPR Reduction Method for LTE OFDMA Systems
Long term evolution (LTE) is the last step toward the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile telephone networks. LTE has adopted orthogonal frequency division multiplexing (OFDM) for the downlink transmission. OFDM meets the LTE requirement for spectrum flexibility and enables cost-efficient solutions for very wide carriers with high peak...

LTE (long term evolution) is come to meet our desired high speed data communication.LTE is the last step toward the 4th generation (4G) of radio technologies designed to increase the capacity and speed of mobile telephone networks. Where the current generation of mobile telecommunication networks are collectively known as 3G (for "third generation"), LTE is marketed as 4G. LTE uses Orthogonal F...
متن کاملA Sub-µW Tuneable Switched-Capacitor Amplifier-Filter for Neural Recording Using a Class-C Inverter
A two stage sub-µW Inverter-based switched-capacitor amplifier-filter is presented which is capable of amplifying both spikes and local field potentials (LFP) signals. Here we employ a switched capacitor technique for frequency tuning and reducing of 1/f noise of two stages. The reduction of power consumption is very necessary for neural recording devices however, in switched capacitor (SC) cir...
متن کاملSc-fdma -an Efficient Technique for Papr Reduction in Uplink Communication Systems -a Survey
In this paper, a survey on different modulation schemes having lowest peak to average power ratio (PAPR) value for use in uplink communication has been studied. OFDM has become the popular modulation choice for high data rate wireless communication systems. It can provide multi-path delay spread tolerance and is robust to channel dispersions. But one of the major limitations of OFDM is the larg...
متن کاملCPM-SC-IFDMA−A Power Efficient Transmission Scheme for Uplink LTE
In this thesis we have proposed a power efficient transmission scheme, CPMSC-IFDMA, for uplink LTE. In uplink LTE, efficiency of the transmitter power amplifier is a major concern, as the transmitter is placed in the mobile device which has limited power supply. The proposed scheme, CPM-SC-IFDMA, combines the key advantages of CPM (continuous phase modulation) with SC-IFDMA (single carrier freq...
