In this paper, we characterise the joint interference alignment (IA) and power allocation strategies for a K-user multicell multiple-input multiple-output (MIMO) Gaussian interference channel. We consider a MIMO interference channel with blind-IA through staggered antenna switching on the receiver. We explore the power allocation and feasibility condition for cooperative cell-edge (CE) mobile u...

In this paper, we study the emergence of topological interference alignment and the characterizing features of a multi-user broadcast interference relay channel. We propose an alternative transmission strategy named the relay space-time interference alignment (R-STIA) technique, in which a K -user multiple-input-multiple-output (MIMO) interference channel has massive antennas at the transmitter...

—Interference alignment (IA) is one of the promising technologies to solve the co-channel interference in wireless communication systems. It can effectively improve system capacity and reliability. Based on consideration of engineering applications, the realization of interference alignment for threecell MIMO cooperative communication system is studied and then a precoding matrices group selec...

Inter-cell interference leads to severe performance degradation in cellular networks, and the study of multi-user interference channel is the corner stone for solving this problem. Amplitude-space layered interference alignment (IA), as an effective complementation to the vector-space IA, is a promising method to increase the data rate in static interference channels. However, recent studies of...

To provide high date rate for indoor services and communication, femtocells and microcells are planned in LTEAdvance system but main problem is how to reduce the interference between micro and femto cells and in the middle of the femtocells. In this paper we proposed regional Average channel state (RACS) to estimate the influence of interference and then we proposed hybrid clustering based on i...

This Chapter focuses on co-channel interference in cellular TDMA networks. Both the generation of co-channel interference and the appropriate interference suppression methods are considered. Contributions of frequency reuse, spatial filtering and time domain interference cancellation on the residual interference are described. Effects of variable propagation parameters (especially lognormal sha...

| A coherent CPM detector based on a reduced lter bank and a reduced state Viterbi decoder is proposed. Bit error probabilities of this detector for some CPM schemes satisfying a speciic narrow spectrum requirement mask are simulated for the AWGN channel. The performance for one of the good candidates is then further evaluated for the case when co-channel and adjacent channel interference is pr...
