Long Term Evolution (LTE) a Third Generation Partnership Project (3GPP) is developed for multimedia applications on mobile user equipment with very high data rates of the order 75/300 Mbps and low latency of 10msec. The high data rates are achieved by using SC-FDMA radio access mechanism for uplink communication and OFDM access mechanism for downlink. […]

Second-Order Cyclostationarity-Based Detection of LTE SC-FDMA Signals for Cognitive Radio Systems
In this paper, we investigate the detection of long-term evolution (LTE) single carrier-frequency division multiple access (SC-FDMA) signals, with application to cognitive radio systems. We explore the second-order cyclostationarity of the LTE SC-FDMA signals and apply results obtained for the cyclic autocorrelation function to signal detection. The proposed detection algorithm provides a very good performance under various […]
Read moreIn this paper, we address dynamic spectrum access for Primary Operators (POs) for LTE-Advanced systems. We propose a dynamic spectrum access framework that exploits the capabilities of carrier aggregation to efficiently utilize the unutilized spectrum which varies with time and space when static spectrum access policies are adopted. A spectrum owner (SO) adopts an auction scheme […]
Read moreThis letter proposes a solution to the multicast subgroup formation problem that aims to maximize the aggregate data rate in Long Term Evolution (LTE) and beyond systems. We analytically demonstrate that, by reducing the solution search space and releasing some constraints, the problem can be solved in a closed form, and a very small number […]

A Predictive Resource Allocation Algorithm in the LTE Uplink for Event Based M2M Applications
Some M2M applications such as event monitoring involve a group of devices in a vicinity that act in a co-ordinated manner. An LTE network can exploit the correlated traffic characteristics of such devices by proactively assigning resources to devices based upon the activity of neighboring devices in the same group. This can reduce latency compared to waiting […]
Read moreThis paper proposes a novel interference-resistant receiver for wideband long-term evolution (LTE) system which employs orthogonal frequency division multiple access (OFDMA) for the downlink. In case the received spectrum is underutilized, compressed sensing (CS) enables us to operate at a sub-Nyquist sampling rate for lower device cost, higher data transmission rate and faster spectrum sensing […]
Read moreThe fastest growing of multimedia services over future wireless communication systems demands more network resources, efficient delivery of multimedia service with high user satisfaction, and power optimization of user equipments (UEs). The resources and power optimization are significant in future mobile computing systems because emerging multimedia services consume more resources and power. The 4G standard […]
Read moreIn this letter, a wideband semisolid skin-equivalent phantom with dielectric properties close to human skin in the V and W band is proposed. The constituents of the phantom are deionized water, agar, and gelatin powder. The phantom has been fabricated and validated by an open ended waveguide method. Since it comprises of low-cost constituents and […]

A stochastic geometry analysis of inter-user interference in IEEE 802.15.6 body sensor networks
Inter-user interference deteriorates reliable communication in body sensor networks (BSNs) when multiple BSNs are transmitting simultaneously in close proximity to each other. Stochastic geometry provides a natural way of modeling the placement of interferers, by averaging over all potential geometrical realizations for the interferers. This paper presents a stochastic geometry analysis of inter-user interference in IEEE 802.15.6 BSNs. The […]
