Interference Cancellation and Avoidance


Multiuser communications systems are inherently interference limited: as the number of users grows, multiple access interference increases, severely hindering the system's capacity. Therefore, there exists a need for efficient algorithms that cancel, limit, avoid or reduce interference.

MPRG has conducted extensive research in the field of interference cancellation over the last several years.  Recently we have initiated work in interference avoidance and management.  This page presents some of this work.  The work can be broadly divided into two areas.

Interference Cancellation

  • Multiuser detection

Interference Avoidance/Management

  • Power Control

  • Multi-user Scheduling

  • Network-Based Characterization & Management of Interference in IEEE 802.11 WLANs
