In a densely deployed small-cell network, part of small-cell base stations (BSs) are activated to serve users while the rest are sleep to save energy. The uplink performance region is studied here for such network employing orthogonal frequency-division multiple access. The authors characterise the limit of performance region using the Pareto boundary. This boundary describes all achievable performance...
Cooperative OFDM transmission is an efficient solution to combat wireless channel fading and to increase system throughput in future board communication. In this paper, we consider the uplink scenario of a cellular cooperative OFDM network, in which multi-relays can forward the source's message to base station. The uplink throughput is optimized by using decode-and-forward (DF) opportunistic relaying...
