Cooperative Game Theory and the Gaussian Interference Channel

Amir Leshem, Ephraim Zehavi
2008 IEEE Journal on Selected Areas in Communications  
In this paper we discuss the use of cooperative game theory for analyzing interference channels.  ...  We also show that the same results are applicable to interference channels where only statistical knowledge of the channel is available.  ...  Typically when the NE is non-unique, the interference is stronger than the desired signal, e.g., in the 2x2 case.  ...

CHANNEL ESTIMATION IN LTE DOWNLINK

2015 International Journal of Advance Engineering and Research Development  
Pilot-assisted channel estimation is a method in which known signals, called pilots, are transmitted along with data to obtain channel knowledge for proper decoding of received signals.  ...  Since downlink is always an important factor in coverage and capacity aspects, special attention has been given in selecting technologies for LTE downlink.  ...  This will result in inter-symbol interference as well as inter-carrier interference. To combat these interferences and to overcome time dispersion of radio channel, CP is used 35 in OFDM system.  ...

Extended Jointly Gaussian Approach for Iterative Equalization

M. Jar, C. Schlegel
2010 2010 IEEE International Conference on Communications  
This figure of merit shows that a significant increase in througput can be obtained by removing some terms from the interference pool, specially for MIMO channels.  ...  A novel equalization scheme for signals transmitted over multipath Multiple-Input Multiple-Output (MIMO) channels, well-suited for iterative processing, is proposed in this work.  ...  MLSE is optimal in the sense of resulting in the smallest possible Bit Error Rate (BER) [4] . However, its complexity grows exponentially with the memory of the channel.  ...

Interference Mitigation via Joint Detection

Jungwon Lee, Dimitris Toumpakaris, Wei Yu
2011 IEEE Journal on Selected Areas in Communications  
This paper addresses the design of optimal and near-optimal detectors in an interference channel with fading and with additive white Gaussian noise (AWGN), where the transmitters employ discrete modulation  ...  It is then demonstrated by analysis and by simulation that in an AWGN channel, while interference-ignorant and successive interference cancellation detectors are both prone to error floors, the optimal  ...  Thus, one might expect that treating interference as noise is optimal when the interference is low, while SIC is optimal when the interference is high.  ...
