The transmission system of wireless communication is induced the channel noise. The potential sources of any noise type, which make and diturb the transmission system in external or internal to the communication system for message delivering. The carrier signal mixed interference signal using the amplitude-locked loop (ALL) can be adopted to separat the co-channel system by operating at same fr...

An analysis for the downlink of coded OFDMA on a Rayleigh-fading channel, with an arbitrary number of Rayleigh faded co-channel interferers of different powers, is presented. Closed-form expressions for the cdf, pdf, and mgf of the signal-to-noise plus interference ratio in the detector are derived. For the case of perfect interleaving, an analysis for the BER performance for soft-decision deco...

The overlap of transmission ranges among multiple Wireless Body Area Networks (WBANs) is referred to as coexistence. The interference is most likely to affect the communication links and degrade the performance when sensors of different WBANs simultaneously transmit using the same channel. In this paper, we propose a distributed approach that adapts to the size of the network, i.e., the number ...

Femto-cells deployment in today’s cellular networks came into practice to fulfill the increasing demand for data services. It also extends the coverage in the indoor areas. However, interference to other femto and macro-cells users remains an unresolved challenge. In this paper, we propose an interference mitigation scheme to control the cross-tier interference caused by femto-cells to the macr...

Due to discrete reuse cluster sizes, disjoined and uniformed channel assignment, conventional tri-sectored cellular systems have not taken full advantage of antenna directivities. In this paper, we present a novel Channel Alternation and Rotation (CAR) scheme to coordinate channel assignment with antenna directivities. In CAR, cell layout is based on two-tier cell-reuse structure and each cell ...

Methods for interference mitigation and adaptive multi-user resource allocation are among the most promising technological breakthroughs that should improve capacity of the last generation broadband wireless systems. In multi-cell scenarios characterized by radio technologies based on OFDMA (Orthogonal Frequency DivisionMultiple Access), co-channel interference is the performance limiting facto...

The suppression of the dominant co-channel interference by joint demodulation is a potential technique to enhance the performance of the future TDMA based mobile systems. The requirements for joint demodulation are that the dominant interfering signal is identified in the receiver and reliable channel estimates are provided for both co-channel signals. In practice to meet both requirements the ...
