چکیده
Abstract—Previous studies on analog network-coded two-way relay (ANC-TWR) assumed the same modulation and coding both for the mobile terminal (MT)-relay station (RS) link and the base station (BS)-RS link. In this paper, we propose an adaptive ANC-TWR, where adaptive modulation and coding (AMC) is employed in order to maximize the uplink (MT-RS-BS) and downlink (BS-RS-MT) throughputs. The single-carrier transmission with frequency-domain equalization (SC-FDE) is utilized for the uplink and the orthogonal frequency division multiplexing (OFDM) is utilized for the downlink. We evaluate, by the computer simulation, the throughput performance of adaptive ANC-TWR. It is shown that the adaptive ANC-TWR achieves better throughput performance than the non-adaptive ANC-TWR with fixed modulation and coding.

Rotationally Invariant Coded Modulation for Physical Layer Network Coding in Two-way Relay Fading Channel
This paper investigates a novel coded modulation scheme for Physical Layer Network Coding (PLNC) in the Two-Way Relay (TWR) fading channel. Using a fully-adaptive adaptive soft demodulator and Independent Decoding Levels, the proposed scheme can eliminate the effect of fading on the TWR Channel. To reduce system complexity at the relay, we also provide a low-complexity scheme with a series of f...
متن کاملLinear Analog Network-Coded OFDM in Two-way Relay Channels
We study analog network-coded (ANC) orthogonal frequency division multiplexing (OFDM) in two-way relay channels and propose three linear analog network coding (LANC) schemes. Motivated by the fact that higher frequency diversity has been made available in the frequency-selective ANC two-way relay channels, the proposed LANC is applied to the frequencydomain OFDM signals with unitary matrices. T...

This paper aims at investigating the superiority of power allocation strategies, based on calculus of variations in a point-to-point two-way relay-assisted channel incorporating the amplify and forward strategy. Single and multilayer coding strategies for two cases of having and not having the channel state information (CSI) at the transmitters are studied, respectively. Using the notion of cal...

We propose non-regenerative multi-way relaying where a half-duplex multi-antenna relay station (RS) assists multiple singleantenna nodes to communicate with each other. The required number of communication phases is equal to the number of the nodes, N. There are only one multiple-access phase, where the nodes transmit simultaneously to the RS, and N − 1 broadcast (BC) phases. Two transmission m...
