Two-way relaying systems efficiently accomplish transmissions in both directions within dual-hop, hence, two time slots can be saved compared with one-way relaying. However, the conventional two-way relaying protocol requires the assumption of symmetric traffic demands, that is, each transmitter node has to act as a receiver in latter slot. This assumption restricts applying two-way relay to general...
Limited feedback for precoding matrices is very practical in the multiple-input multiple-output antenna communication system. In this paper, a capacity criterion is proposed to design the precoding codebook, which emphasizes the negative impacts of the limited feedback and maximizes the capacity directly. Then, the generalized Lloyd algorithm is used to construct the precoding codebook according to...
