摘要：

This paper is concerned with the performance analysis of a dual-hop random access network in underwater communication environment. Single gateway equipped with multiple antennas, and employing zero-forcing technique in a space division nmltiple access scenario, is connected a random number of independent sources which are hidden from their destination(s). The sources are located underwater, and the only mean to connect them with their destination(s) is through a gateway, which acts as amplify and 14ward relay. We developed accurate mathematical models for the multiple access interference which take into account, in addition to the statues of each source (active/idle), the effects of fading and additive noise at both the gateway and destination(s). A new unified mathematical method is developed, which leads to the derivation of new analytical expressions 14 the overall spectral-efficiency. The accuracy of the new mathematical results is confirmed by Monte Carlo simulation.
