Coded cooperation: generalised outage analysis
نویسندگان
چکیده
In this study, the authors derive the exact closed-form expression of the outage probability for coded cooperation using power-based approach. They consider a generalised system model with n relays (n > 1) over Nakagami-m fading channels. They also obtain the optimal number of relays for the given outage performance. Furthermore, they find analytically the critical cooperation ratio at which the total outage probability is minimum.

Outage probability of coded cooperation for slow fading channel
This letter presents the outage probability of the Reed Solomon (RS) coded cooperation scheme. In this scheme, the codeword of the Users are partitioned into two frames and transmitted through two independent fading channels. The first frame is transmitted directly to the base station. The second frame is transmitted via a partner to the base station. The derived outage expressions confirm that...
متن کاملReed Solomon Coded Cooperation Scheme in Mobile Communication Networks and Application
Coded cooperative communication technique utilizes single antenna mobiles in a multiuser environment that share their antennas and incorporates channel coding in order to achieve transmit diversity. This thesis presents a new coded cooperation scheme based on Reed Solomon (RS) codes. The RS codes are very effective in correcting random symbol errors and random burst errors over wireless fading ...
متن کاملPerformance Analysis for Coded Cooperative Multiple-relay Channels
In order to achieve improved diversity over the classical coded cooperation method in fading channels, we consider a coded cooperation strategy based upon rate-compatible punctured convolutional codes, which is suitable for wireless multiple-relay channels. Outage probability expressions for the coded cooperation protocol with multiple relays are derived, which characterize the performance of a...
متن کاملPerformance Analysis of Hybrid Coded Cooperation in Wireless Networks
Relay-assisted transmission schemes for wireless networks are continuing to grow because of their potential of providing the benefits of space diversity. This paper applies hybrid relaying protocols to coded cooperation which is a combined scheme of user cooperation and channel codes. The hybrid relaying protocol adaptively uses the amplify-and-forward and decode-and-forward whether a relay dec...

In this paper, a dual-hop cooperative diversity land mobile satellite system (LMSS) respectively adopted amplify-and-forward (AF), decode-and-forward (DF), and coded cooperation (CC) relaying protocols is proposed, and the outage probability behaviors of the three protocols have been analyzed. We use the signal to noise ratio (SNR) of each path to derive the closed-form expressions of outage pr...
