Outage Probability and Power Allocation for Two-Way DF Relay Networks with Relay Selection
In this paper, we investigate the outage probability and power allocation for the two-way decode-andforward (DF) relay networks with relay selection. Specially, we consider independent but not necessarily identical distributed Rayleigh fading channels. Firstly, we derive an exact closed form outage probability expression. To shed light on the relation between the outage probability and the powe...
متن کاملPerformance analysis of joint relay selection and transmission schemes in multiple-antenna two-way relay systems
In this paper, we consider a two-way relay system with two multi-antenna sources and multiple single-antenna relays and study the performances for various transmission schemes with the assumption that perfect channel state information (CSI) is available at both the sources and the relays. Although a transmission scheme that combines source beamforming and relay selection (BF-RS) is known to imp...
متن کاملEffect of Relay Location on Two-way Df and Af Relay in Lte-a Cellular Networks
Wireless multi-hop relay systems are important technologies in mobile communications. These systems ensure high-speed data transfer and extended coverage area at a low cost. This paper investigates the position of a relay problem for the maximum capacity enhancement of a twoway Relay Node (RN) to achieve an efficient and scalable Long Term Evolution-Advanced (LTE-A) wireless network design. The...
متن کاملError Performance Analysis of DF and AF Multi-way Relay Networks with BPSK Modulation
In this paper, we analyze the error performance of decode and forward (DF) and amplify and forward (AF) multi-way relay networks (MWRN). We consider a MWRN with pair-wise data exchange protocol using binary phase shift keying (BPSK) modulation in both additive white Gaussian noise (AWGN) and Rayleigh fading channels. We quantify the possible error events in an L-user DF or AF MWRN and derive ac...
متن کاملPerformance Analysis of Two-Way AF Cooperative Networks with the Nth Relay Selection
In this letter, we propose a novel two-way amplifyand-forward (AF) relay selection scheme over independent flat Nakagami-m fading channels. In the proposed schemes, two users first sequentially broadcast their respective information to all the relays. Then, the Nth best-relay perform AF protocol on the received signals sent from the two users and forward them to both users. The Nth best-relay i...
