“…Two‐way relay (TWR) technique has been a hot research topic in recent years , , among which relaying schemes based on decode‐and‐forward (DF) and amplify‐and‐forward (AF) have become two of the most popular relaying strategies (cf. Figure 16 in ). As shown in Figure , the conventional bi‐directional relay (CBR) protocol requires four time slots for the transmission of two data packets.…”

The two-way relay (TWR) protocols are efficient in providing appreciable throughput gains in wireless networks through the use of network coding to combine packets from multiple channels. The key determinant factor in driving the throughput improvement is the degree of simultaneity achieved in the relay scheme. In this paper, we propose a new TWR protocol named interference cancellation TWR (IC-TWR), which combines network coding, spatial diversity, and IC techniques to arrive at high degree of simultaneity and in the meanwhile to relax the requirement on channel state information as compared with TWR schemes based on amplify-and-forward. Numerical analysis shows that the proposed IC-TWR is uniformly advantageous over the traditional decode-and-forward scheme in terms of system throughput and end-to-end delay. The proposed scheme may be useful for system designers of high-speed multimedia applications in wireless mobile networks, wireless cellular networks, wireless sensor networks, and so on.

“…At relay, maximum likelihood decoding (MLD) algorithm is applied to decode the signals. After decoding, the relay uses network coding [2][3] to merge the decoded signals, makes STC design according to the antenna number, and broadcasts them to the destination. The receiver achieves space-time diversity by using joint decoding technology to reduce the computational complexity.…”

In this paper, a novel cooperation space-time network coding (CSTNC) scheme based on multi-sources distributed cooperative network is considered. In this scheme, multiple sources transmit signals to relay and destination node. The relay re-encodes the decoded signals through space-time network coding with the aid of multiple antennas. The simulation shows that the BER, capacity and outage probability of the CSTNC becomes better with the increasing of relay antenna number and very close to traditional space-time network coding (TCSTC) scheme. Meanwhile, transmission efficiency analysis demonstrates that CSTNC scheme has higher transmission rate.

Summary This paper focuses on noncoherent detection scheme for multiple‐input multiple‐output two‐way relay channel network with two two‐antennas source nodes and one single‐antenna relay node. An orthogonal differential space–time network coding (ODSTNC) scheme based on relay detection and forward protocol is proposed. The proposed scheme combines space–time coding with network coding, and the differential modulation and detection are used in both multiple access stage and broadcast stage. The multiple‐symbol differential detection is employed at the relay. The maximum likelihood decision and its low‐complexity sphere decoding decision are given. The upper and lower bounds on the average symbol error probability for this system under differential binary phase shift keying (DBPSK) are derived, and a diversity order of 2 is confirmed to be achieved. The simulation results show that the ODSTNC scheme has good performance, and it is available for the applications of far distance signal transmission between two terminals where channel state information is unknown.
