This paper presents a performance model of a wireless network with one-antenna transmitter scheduling information towards a set of terminals in a time-division fashion. Each terminal is enabled with a multiple-antenna maximum ratio combining (MRC) receiver. The objective of this model is to evaluate the performance of adaptive modulation and coding (AMC) in Rayleigh fading channels under two assumptions:...
The deployment of small-cells along a macro-cell is considered to be an effective solution in order to increase the capacity and offload the traffic from the macro-cell system. In current heterogeneous configuration with large number of deployments, it is likely that the small-cells will coexist with macro cells over the same spectrum as additional spectrum licenses are difficult and expensive to...
Radio frequency (RF) energy harvesting is an emerging technology that will enable to drive the next generation of wireless sensor networks (WSNs) without the need of using batteries. In this paper, we present RF energy harvesting circuits specifically developed for GSM bands (900/1800) and a wearable dual-band antenna suitable for possible implementation within clothes for body worn applications....
With the widespread deployment of LTE 4G systems and large number of connected devices due to the Internet of Things, M2M services using LTE is under consideration by many cellular operators. In LTE Rel-12, low cost M2M devices with material cost comparable to EGPRS devices are being introduced. In addition, coverage enhancement techniques, which would be required to support M2M, will be standardized...
With the widespread deployment of LTE 4G systems and large number of connected devices due to the Internet of Things, M2M services using LTE is under consideration by many cellular operators. To provide ubiquitous network coverage for M2M services, 3GPP will introduce coverage enhancement feature in Rel-13. In this paper we analyze features which will extend the range of an LTE system by up to 15dB...
