Long-term evolution-advanced (LTE-A), the true 4G technology of third Generation Partnership Project family, has a new feature that aggregates multiple LTE carriers so that users can be served on multiple component carriers (CCs). This characteristic plays an important role to increase data rate multiple times for LTE-A users with corresponding multiple CCs. However, current proposed packet scheduling (PS) algorithms ignore this effect in the effort of providing new solution that increases system performance. The modified proportional fair algorithms proposed in this study can provide optimised algorithm for PS mechanism in LTE-A system as well as other technologies that use multiple carriers.

A compact planar multiband antenna for 3G/4G mobile terminals is presented. The proposed design consists of a Sierpinski Gasket fractal geometry perturbed according to a Particle Swarm optimization (PSO) strategy in order to operate in advanced wireless services (AWS-1, 1710-1755 MHz, 2110-2155 MHz) and worldwide interoperability for microwave access (WiMAX, 3300-3600 MHz) bands. Numerical and experimental results assess the effectiveness of the proposed prototype in its multiband operations fitting the project constraints.

“…It has been used in the 4th and possible future generation mobile broadband wireless access systems such as LTE and WiMAX [1,2]. However, there are some major disadvantages associated with OFDM transmission, such as large peak-toaverage power ratio (PAPR), significant out-of-band emission (OOBE), and sensitivity to carrier frequency offset (CFO) and phase noise.…”

This paper proposes a comprehensive solution to reduce peak-to-average power ratio (PAPR), cancel out-of-band emission (OOBE), and alleviate the impact of phase noise for precoded orthogonal frequency-division multiplexing (OFDM) systems. Making use of the cancellation and pilot symbols and subcarriers in both data and frequency domains, this solution integrates a number of novel schemes to overcome OFDM's inherent drawbacks and mitigate practical impairments for high speed wireless communications. These schemes include a layered precoding structure, a low complexity OOBE cancellation using both data domain cancellation symbols and frequency domain cancellation subcarriers, and an effective phase noise compensation using data domain pilot symbols. The improved overall system performance of the proposed solution is verified by simulation results.Index Terms-High speed wireless transmission, OFDM, peakto-average power ratio, out-of-band emission, and phase noise.
