“…It is clear that the proposed MMSE-BD outperforms the conventional ZF-based BD methods such as the enhanced ZF (E-ZF) [13] and the pair-aware ZF (PA-SDR) [12]. From the circle line for the SDMA [10], we confirm that no SIC is optimum, i.e., U opt = 0 2K , at low SNR as proved in Lemma 1.…”

“…Since the problem (4) is neither convex nor concave with respect to the relay matrix Q, a direct rate optimization may require high computational cost even for finding a local optimal solution [13]. To tackle the problem, traditionally, low complexity alternatives such as ZF and MMSE methods have been widely adopted in wireless communications.…”

“…The channels in the receive signal equations (1) and (3) in [33], the circuit powers of each antenna in relay and UE are 0.97 dBW and −13 dBW, respectively. We consider the scenarios of K ∈ {1, 2, 3} pairs and (M, N R ) ∈ { (1,8), (2,4), (4, 2)}, i.e. the total number of antennas is fixed at 8 but the number of relays is M ∈ {1, 2, 4}.…”

“…In particular, following the idea of [5], the DoF of several multi-way relay networks were studied in [6]- [8], [11] where they only tackled with networks with special number of antennas, so that the signals carrying every two pairwise symbols can be aligned at the relay. Thus, their results, requiring one-to-one alignment only, are established in a relatively straightforward manner.…”
