Introduction to Interference Alignment on the Deterministic Interference Channel


In a typical wireless communication scenario, several user pairs desire to convey error-free, independent information simultaneously. With an increasing number of users, the achievable rates of presently used multiple-access schemes are diminishingly low.

Due to this bottleneck, the idea of Interference Alignment adresses the combined design of signals and interferences. The surprising result reveals that - with proper coding - many interfering users can be aligned in such a way that they behave as a virtual, single interferer and conserve higher rates.

The upcoming deterministic channel model provides an abstract perspective to investigate the properties of interference alignment.

In this talk, the basic concepts of Interference Alignment on a deterministic channel model is comprehensively introduced. Also, a first algorithm and simulation results are presented.
