Adaptive limited feedback for interference alignment in MIMO interference channels
It is very important that the radar sensor network has autonomous capabilities such as self-managing, etc. Quite often, MIMO interference channels are applied to radar sensor networks, and for self-managing purpose, interference management in MIMO interference channels is critical. Interference alignment (IA) has the potential to dramatically improve system throughput by effectively mitigating ...
متن کاملIterative Transceiver Design for Opportunistic Interference Alignment in MIMO Interfering Multiple-Access Channels
—In this paper, we propose an iterative transceiver design algorithm for opportunistic interference alignment in MIMO interfering multiple-access channels. The proposed algorithm iteratively optimizes the transmit beamforming vectors, the receive matrices and the user selection set, which digs into the multiuser diversity gain. Specifically, data transmission can be operated in each iteration ...
متن کاملInterference Alignment with Limited Feedback on Two-cell Interfering Two-User MIMO-MAC
In this paper, we consider a two-cell interfering two-user multiple-input multiple-output multiple access channel (MIMO-MAC) with limited feedback. We first investigate the multiplexing gain of such channel when users have perfect channel state information at transmitter (CSIT) by exploiting an interference alignment scheme. In addition, we propose a feedback framework for the interference alig...
متن کاملNoncooperative Multimode Precoding with Limited Feedback in MIMO Interference Channels
In a K-user N×N MIMO interference channel, each user achieves N/2 degrees of freedom through the concept of interference alignment [1], which utilizes the reciprocity of wireless channels. In nonreciprocal MIMO interference channels, [1] needs huge feedback overhead since each receiver should inform each transmitter how much interference it induces. When the bandwidth of the feedback channel is...
متن کاملMulti-Input Multi-Output MLP/BP-based Decision Feedback Equalizers for Overcoming Intersymbol Interference and Co-Channel Interference in Band-Limited Channels
This paper presents a multi-input multi-output (MIMO) multi-layered perceptron neural network with backpropagation algorithm (MLP/BP). The proposal is a waveform equalizer for distorted nonreturn-to-zero (NRZ) data recovery in band-limited channels with co-channel interference (CCI). From the simulation results, we note that the proposed design can recover severe distorted NRZ data as well as s...
