摘要： Systems and methods for assigning pilot sequences include randomly assigning pilot sequences to a population of access terminals. A first pilot sequence assigned to a worst performing access terminal of the population of access terminals is updated to a different pilot sequence that improves performance of the worst performing access terminal. A second pilot sequence assigned to a best performing access terminal of the population of access terminals is updated to another pilot sequence that reduces performance of the best performing access terminal.

摘要： A transmission protocol for a multi-way massive MIMO relay system uses linear processing, self-interference cancelation and successive cancelation decoding to significantly reduce the number of time-slots required for data exchange amongst user devices compared to that for the conventional data transmission protocol. As a result, the spectral efficiency of the system is significantly increased.
