Considering a cooperative multicast system where 2 sources transmit data to 2 users with the help of 1 relay (2-1-2), the performance of a network coded cooperative (NCC)transmission scheme is evaluated. Due to the use of network coding, more than one source node can be served simultaneously by one cooperative transmission. As a result, the time resource consumed by the cooperative transmission is...
Broadcast nature of wireless networks can be exploited to provide a flexible transmission, especially in multicast service. The potential relay then is capable to participate in message forwarding. This paper presents a network coding based cooperative (NCBC) multicast scheme exploiting limited feedback. In the developed NCBC multicast scheme, the source transmits two separate signals to multiple...
Linear equalizers (LEs) have been widely adopted for practical systems due to their low computational complexity. However, it is also well known that LEs provide inferior performance relative to a maximum-likelihood equalizer (MLE) or other near-MLEs, because LEs usually cannot collect the diversity order enabled by the transmitter and at the same time they lose mutual information. More importantly,...
