Outage Performance for Two-Way Relaying with Co-Channel Interference and Channel Estimation Error

—In this paper, we consider the outage performance of a two-way decode-and-forward relaying network in the presence of multiple strong interferers at the source/destination terminals and channel estimation errors. We define the signalto-noise ratios and signal-to-interference ratios and then use them to derive closed-form expressions for the outage probability of the system under the symmetric...

Co-Channel Interference Mitigation in Multiuser Systems with Unknown Channels

This paper studies signal detection in multiuser systems where the uncertainty is due to fading as well as a strong co-channel interference of the same form as that of the desired signal. In particular, unlike for the desired signal, no pilot for the interference signal is available for measuring its fading channel state. Still, the interference is a non-Gaussian process and treating it as Gaus...

Data Detection in MIMO Systems with Co-Channel Interference

The Bell Labs Layered Space-Time (BLAST) architecture has been proposed to achieve high spectral efficiency on multi-input multi-output (MIMO) channels. Most studies of the BLAST algorithm consider spatially and temporally white noise and interference at the receiver. In this paper, we study channel estimation and data detection of a MIMO system under both spatially and temporally colored inter...

Co-Channel Interference

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...
