Title
Ergodic Spatial Nulling For Achieving Interference Free Rates
Abstract
It is shown that a receiver equipped with two antennas may null an arbitrary large number of spatial directions to any desired level, while maintaining the interference-free signal-to-noise ratio, by judiciously adjusting the distance between the antenna elements. The main theoretical result builds on ergodic theory. The practicality of the scheme for systems operating at a moderate signal-to-noise ratio is demonstrated for a scenario where each transmitter is equipped with a single antenna and each receiver has two antenna elements, the separation of which can be arbitrarily set. As an example, for a five-user planar line-of-sight interference channel, with the directions of users being uniformly distributed, at a signal-to-noise ratio of 10 dB, a near interference-free average transmission rate is achievable. This amounts to roughly doubling the average rate attained by non-naive time-division multiple access.
