The paper analyzes the performances provided by two algorithms that combine the network and distributed channel coding in cooperative schemes with a relay-node serving two mobile stations, placed symmetrically and asymmetrically vs. the base-station. The analysis is performed in scenarios that consider error-affected mobile -relay node channels. It also proposes a low complexity hybrid coded cooperation algorithm that employs adaptively the cooperative or the non-cooperative transmissions. The selection of the cooperation mode is based on the bit error probability estimation on the mobile -relay node channels.

This paper analyzes the performance provided on the uplink connection by a cooperative cluster, composed of user terminals and relays, which employ a XOR-based network coding algorithm. The paper presents the construction of the graphs that describe the operation of the algorithm within the selected topology. It then provides a theoretical analysis of the performance ensured by this algorithm in terms of the outage probability. The Block Error Rate (BLER) performance of the user terminals involved in cooperation are also evaluated for two cooperation topologies characterized by different cooperation graphs.
