Abstract
Embodiments herein disclose an Interference Cancelling Block Modulation (ICBM), a new open-loop precoding scheme where each transmitter is assigned with a predetermined precoder which facilitates interference cancellation at the receivers. Only a finite set of precoders will be used, and they will be assigned to each transmitter in a pre-determined manner. Usually, interfering transmitters located adjacent to each other will have different precoders, and the same precoder can be reused by non-adjacent transmitters. The precoders are represented by N×K matrices and they expand the symbols in time and/or frequency by a factor of N/K while providing precoded sequences with low cross-correlation properties.
