Communication between two multi antenna full duplex transceivers using bidirectional MIMO links faces a major problem of self-interference of signals. Suppression in spatial domain and cancellation in time domain are the two methods that can be adopted to mitigate the self-interference. In suppression, self-interference is mitigated at the cost of spatial degrees of freedom unlike in cancellation where the signal responsible for self-interference is subtracted. The rate regions obtained by both the methods are compared and in case of suppression, the spatial multiplexing order is varied at each node and comparison between rate regions achieved by different stream configurations is made. The results characterize the significant difference in the rates achieved after implementing cancellation and suppression. © School of Engineering, Taylor’s University.
