Symmetric Deterministic Interference Channel with Transmitter Cooperation
This work presents novel achievable schemes for the 2-user symmetric linear deterministic interference channel with limited-rate transmitter cooperation and perfect secrecy constraints at the receivers. The proposed achievable scheme consists of a combination of interference cancelation, relaying of the other user’s data bits, time sharing, and transmission of random bits, depending on the rate...
متن کاملMultiuser MIMO Transmitter Optimization for Inter-Cell Interference Mitigation
The optimization of the transmitter precoder (steering vectors and power allocation) for a MIMO Broadcast Channel (MIMO-BC) subject to general linear constraints is considered. These include various types of system constraints such as sum power, per-antenna or per-group-of-antennas power constraints, and “forbidden interference direction” constraints. We consider the transmitter optimization pr...
متن کاملDistributed Interference Cancellation in Multiple Access Channel with Transmitter Cooperation
We consider a two-user Gaussian multiple access channel with two independent additive white Gaussian interferences. Each interference is known to exactly one transmitter non-causally. Transmitters are allowed to cooperate through finite-capacity links. The capacity region is characterized to within 3 and 1.5 bits for the stronger user and the weaker user respectively, regardless of channel para...
متن کاملOn Transmitter-Based Interference Mitigation in TDD-Downlink with Frequency Selective Fading Channel Environment
The capacity of CDMA-based systems, for instance UMTS, is interference limited. The downlink (DL) is expected to carry much more traffic than in the uplink (UL) for multimedia applications services. If the characteristic of the DL channel is a priori known at the base station (BS), preprocessing data before transmission at BS reduces interference at mobile terminals (MTs). This paper investigat...
متن کاملExtended Abstract: Interference Mitigation in Enterprise WLANs through Speculative Scheduling
Wireless LANs are commonplace installations in enterprise environments. Their ease of use and deployment, however, are accompanied by a difficulty in their management and security. Proposed solutions to these problems are based on centralization; in the control plane through centralized authentication and allocation of channels and power levels, and in the data plane through time slotted medium...
