“…In (15), the E 2 received signal power is considered as interference on the reception of E 1 . Since h i is assumed constant over the entire transmission period, and subscriber i failed to decode E 1 in the first phase, therefore |h i | 2 ar −n i P d /N 0 , g 1 e , that is, the interfering signal power does not exceed g 1 e and, therefore, SNR sc,2 e 1 ,i is dependent on the first phase decoding result.…”

Cooperative diversity plays an important role in combating channel fading and increasing reliability of wireless communication links. The main purpose of cooperative diversity is to transmit the same data from multiple sources. Hence, there is no inherent capability in the cooperative diversity schemes to deal with scalable types of data, for example, scalable video coded signals. The authors introduce a two-phase cooperative multicast scheme based on superposition coding to transmit scalable video signals. The new scheme mixes the superposition with cooperative diversity, and chooses the right parameters in both schemes to enhance the system's multicast capability. This study also derives an exact closed-form expression of the average multicast group throughput in case of Rayleigh flat fading channel. The closed-form expression allows system designers to choose the correct cooperation and superposition parameters to satisfy the network operator needs. Simulations show that, in addition to the additional degrees of freedom resulting from using cooperation with superposition, the proposed scheme outperforms the conservative scheme and schemes solely exploiting cooperative relaying or superposition. Simulations show that the new scheme can increase the average network throughput more than four times compared to the conservative scheme.

“…An IPTV channel stream is encoded in two layered bit-streams and a BS allocates a static and different modulation scheme to each layer. In [20], Cooperative Multicast Scheduling scheme was presented to improve the network throughput for IPTV stream transmission. In the first phase of this, the IPTV channel stream is transmitted using dense modulation and high coding rates.…”
