Abstract :
In ad hoc or sensor networks, datas go through several nodes before reaching their destination. Thos nodes can simply be relays that amplify the signal without decoding and coding it (non regenerative relays). However, the transmitted signal after several hops suffers from an important degradation. In this paper we consider the possibility of using non regenerative relays and their impact on additive white gaussian noise, multpaith interference and multiple acces interference. We especially focus on the simple case of a two hops transmission.
