Tutorial: Towards 4G wireless systems (WIMAX &LTE) BR” (4GWS)
2011 Edition, June 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Fourth generation wireless systems have the potential to change the way we communicate and collaborate to accomplish business needs. The need of the hour is to provide a unified system that provides a seamless user experience on the move. Systems beyond IMT-2000 claim to...

IMT-advanced relay standards [WiMAX/LTE Update]
2010 Edition, Volume 48, August 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

There are two candidates for IMT-Advanced (4 G) standards, LTE-Advanced by 3 GPP and 802.16 m by IEEE. This article focuses on relay architectures in 16 m and LTE-A, and discusses design principles and trade-offs leading to decisions in each standards group. Basically, 16 m relay and...

Evolving military broadband wireless communication systems: WiMAX, LTE and WLAN
2016 Edition, May 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Emerging technologies for mobile broadband wireless are being considered as a Commercial Off-The-Shelf solution to cover the operational requirements of the future warfare. The capabilities of these technologies are being enhanced to meet the growing market demands on performance. In this...

WiMAX/LTE receiver front-end in 90nm CMOS
2009 Edition, May 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

RFIC design using low-voltage nanometer CMOS technologies offers both advantages and challenges. This paper describes the limitations of using these technologies in receiver front-end design and proposes circuit solutions. Several techniques such as wideband noise reduction, inductoreless peaking,...

Toward enhanced mobile video services over WiMAX and LTE [WiMAX/LTE Update]
2010 Edition, Volume 48, August 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Wireless networks are on the verge of a third phase of growth. The first phase was dominated by voice traffic, and the second phase, which we are currently in, is dominated by data traffic. In the third phase we predict that the traffic will be dominated by video and will require new ways to...

A Dual-band MIMO Antenna for Bluetooth/WiMax/LTE Applications
2018 Edition, November 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A dual-band microstrip-fed planar MIMO antenna is proposed for application in Bluetooth (2.4 GHz), WiMax (2500MHz/ 3650MHz) and LTE (2570MHz-2620MHz/ 3600MHz-3800MHz) bands. A triangular ring resonator with a split at asymmetry position is used to realize dual-band response. The...

Towards integrating pattern reconfigurable antennas in WiMAX/LTE radios
2015 Edition, April 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The integration and deployment of pattern reconfigurable antenna arrays in real-world wireless systems have been inhibited by the prohibitively high costs of implementation and integration infrastructure. As a result, many research institutions have turned to Software-Defined Radio...

Interference management for 4G cellular standards [WIMAX/LTE UPDATE]
2010 Edition, Volume 48, August 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

4G cellular standards are targeting aggressive spectrum reuse (frequency reuse 1) to achieve high system capacity and simplify radio network planning. The increase in system capacity comes at the expense of SINR degradation due to increased intercell interference, which...

Advanced handover schemes in IMT-advanced systems [WiMAX/LTE Update]
2010 Edition, Volume 48, August 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Handover is one of the key components in cellular network mobility management and has the most stringent latency requirement on service interruption time since the end-user experience is majorly determined by it. In the design of IMT-Advanced systems, the scalability and flexibility to...

Carrier aggregation framework in 3GPP LTE-advanced [WiMAX/LTE Update]
2010 Edition, Volume 48, August 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Carrier aggregation is one of the most distinct features of 4G systems including LTEAdvanced, which is being standardized in 3GPP as part of LTE Release 10. This feature allows scalable expansion of effective bandwidth delivered to a user terminal through concurrent utilization...
