Noncooperative 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 کاملLimited Feedback Precoding for Wireless MIMO Broadcast Channels
Recently, a number of techniques have been introduced to exploit multiuser diversity of a wireless multiple-input multiple-output (MIMO) broadcast channel (BC) that consists of a base station (BS) with t transmit antennas and K mobile stations (MS) with multiple antennas. However, prior works have ignored the rate overhead associated with feedback of MIMO BC channel state information (CSI), whi...
متن کاملAdaptive 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 کاملMimo Based Downlink Channels with Limited Feedback and User Selection Using Th Precoding Technique
The implementation of Tomlinson-Harashima (TH) pre-coding for multiuser MIMO systems based on quantized channel state information (CSI) at the transmitter side. Compared with the results in [1], our scheme applies to more general system setting where the number of users in the system can be less than or equal to the number of transmit antennas. We also study the achievable average sum rate of t...
متن کاملRobust Precoding Formulti-user Miso Systems with Limited-feedback Channels
InMulti User Multiple Input Single Output (MU-MISO) systems one centralized transmitter with multiple antennas serves several decentralized single-antenna receivers. Precoding is an attractive way to remove multiuser interferences because it reduces cost and power consumption in the user equipment. When implementing precoding, however, the base station should know the Channel State Information ...
