In this paper, we propose a novel approach for cooperative systems performance optimization. We are interested on the uplink CDMA communications, known to be both intra-cell and inter-cell interference limited. More precisely, we define a multi-access interference (MAI) cost that reliably quantifies the additional interference generated by a relayed communication to the whole cellular system. For...
In this paper, we propose a novel optimization approach for Amplify-and-Forward (AF) relaying schemes. In previous works, we have optimized the AF relaying scheme carried on a symbol-by-symbol basis. Here, we focus on AF and Incremental AF (IAF) schemes, operating on a packet-by-packet basis. The optimization is carried out while keeping the additional multiple access interference cost, inherent to...
In radio mobile cellular networks, the users located at the cell border suffer from a bad quality of service (QoS). Cooperative communication is a promising technique that can overcome this weakness by allowing these users to profit from powerful benefits of spatial diversity. Nevertheless, abstraction is usually made on the impact of the additional multiple access interference inherent to relaying...
