... transmission in the two-way protocol proceeds as follows: (i) the BS transmits a signal to the relay while the MS is silent, that is, the DL, (ii) the MS transmits its signal to the relay while the BS ... that is, the UL and (iii) the relay jointly processes the DL and UL signals and proceeds to broadcast a unified signal to the BS and MS. After such, the BS and...

... power constraints. Suboptimality of the conventional BD consid- ered in earlier research has been shown, and this has moti- vated the search for the optimal BD scheme. The optimal block diagonalization ... [26–28]. Hence, it is not optimal. The optimal form of BD proposed in this paper includes the optimization over the entire null space of other users’ channel matrices...
