Successive interference cancellation (SIC) scheme is proposed as a new technique that has the potential to reduce the interference and suppress the multiple-access interference (MAI) in spectral-amplitudecoding (SAC) optical-code-division-multiple access (OCDMA) systems. The proposed receiver-based on fiber Bragg gratings (FBGs) techniques. The performance of the proposed system is theoreticall...

One of the fundamental elements impacting the performance of a wireless system is interference, which has been a long-term issue in wireless networks. In the case of cognitive radio (CR) networks, the problem of interference is tremendously crucial. In other words, CR keeps the important promise of not producing any harmful interference to the primary user (PU) system. Thus, it is essential to ...

The anticipated proliferation of various wireless local area network (WLAN) enabled devices in the near future is likely to result in increased mutual interference in the 2.45GHz Industrial, Scientific and Medical (ISM) band. This work investigates the impact of standard Bluetooth and enhanced Bluetooth interference on 802.11g enabled consumer electronic devices and vice versa. Technical design...

In this paper, we propose a methodology for estimating the statistics of the intercell interference power in the downlink of a multicellular network. We first establish an analytical expression for the probability law of the interference power when only Rayleigh multipath fading is considered. Next, focusing on a propagation environment where small-scale Rayleigh fading as well as large-scale e...

We study the performance of the minimum-noisevariance beamformer employing a single electromagnetic (EM) vector sensor that is capable of measuring the complete electric and magnetic fields induced by EM signals at one point. Two types of signals are considered: One carries a single message, and the other carries two independent messages simultaneously. The state of polarization of the interfer...

In the wireless indoor environment, the channel may vary slowly as users and the interferers may move at slow speeds. A frequency hopped CDMA (FH-CDMA) system can adapt to the different interference levels in hopping patterns and assign the slots different bit rates to increase the system capacity. We show that the maximum throughput bit rate/channel assignment problem is NP-hard. Several pract...

Mobile handset carriers are presented as a source of interference to GPS operation in smartphones. The carriers are presented in terms of their analytical form; block level generation as well as their statistical distribution model. In addition, we present the analytical form of the received GPS signal corrupted by carrier interference The Analysis is applied on the chip level in the acquisitio...

The fast computation of blocking probabilities and the resulting capacity is one of the crucial tasks in the planning process of UMTS networks. The admission control in WCDMA networks bases on the momentary interference which includes both own-cell and other-cell interference. Since both interference terms are stochastic values we speak of soft blocking. The number of users in the system is not...

It is a well-known fact that routing metrics play a crucial part in the performance of wireless mesh networks (WMN). When routing protocols are implemented, the routing metrics are assigned to different paths. It calculates the best path to predict the best routing path. They are integrated in routing protocols to improve WMNs efficiency in terms of reliability, latency, throughput, error rate ...

A two-tier UMTS network is considered where a large number of randomly deployed Wideband Code Division Multiple Access (WCDMA) femtocells are laid under macrocells where the spectrum is shared. The cochannel interference between the cells may be a potential limiting factor for the system. We study the uplink of this hybrid network and identify the critical scenarios that give rise to substantia...
