Abstract
A two-way relay transmission apparatus applied to multi-input multi-output communication systems that combines signals received from the terminals and performs a modulo operation to the combined signal to concentrate the signal points towards the center of the constellation. And then, the modulo version of the combined signal is broadcasted. As a result, the peak and average relay transmission powers can be reduced.
