co-channel interference is a major factor in limiting the capacity and link quality in cellular communications. as the co-channel interference is modeled by lognormal distribution, sum of the co-channel interferences of neighboring cells is represented by the sum of lognormal random variables (rvs) which has no closed-form expression. assuming independent, identically distributed (iid) rvs, the...

Co-channel interference is a major factor in limiting the capacity and link quality in cellular communications. As the co-channel interference is modeled by lognormal distribution, sum of the co-channel interferences of neighboring cells is represented by the sum of lognormal Random Variables (RVs) which has no closed-form expression.

This paper studies the problem of centralized dynamic channel assignment (DCA) in wireless cellular systems under space and time-varying channel demand. The objective is to minimize the number of channels required to satisfy demand while also satisfying cochannel interference constraints. Cumulative co-channel interference constraints govern channel reuse, via a threshold decision criterion bas...

Recent information theory results have indicated that a large channel capacity exists for wireless systems with multiple transmit and receive antennas. With different assumptions of channel knowledge and interference knowledge at the transmitter, the channel capacity of multiple input multiple output (MIMO) systems has been studied under both spatially white and colored interference and noise. ...

In this paper we investigate the performance of MIMO systems in co-channel interference. We present a way of explicitly examining the effect of interference on the MIMO sub-channel gains. Using this, we derive upper and lower asymptotic bounds on capacity with many interferers and in high interference-to-noise ratio. Simulation results are presented for these bounds and for the performance of M...

Co-channel interference in Long Term Evolution (LTE) cellular network is caused due to usage of same frequencies between the neighboring cells at the same region. Here the term co-channel interference is otherwise known as inter-cell interference. It is important to mitigate co-channel interference at micro-cells inorder to improve the communication performance of the cellular network. In this ...

High-Quality Detection in Heavy-Traffic Avionic Communication System Using Interference Cancellation Techniques by Minh Nguyen This dissertation focuses on quantifying the effects of multi-user co-channel interference for an avionic communication system operating in a heavy-traffic aeronautical mobile environment and proposes advanced interference cancellation techniques to mitigate the interfe...

Recently, we proposed an interference-aware channel segregation based dynamic channel assignment (IACS-DCA). In IACS-DCA, each base station (BS) measures the instantaneous co-channel interference (CCI) power on each available channel, computes the moving average CCI power using past CCI measurement results, and selects the channel having the lowest moving average CCI power. In this way, the CCI...
