In this paper, we propose a cross-layer design that combines antenna selection and adaptive modulation strategies in a HSDPA context. In order to optimize system performance, in terms of link throughput, both the optimal transmit antenna subset and the corresponding constellation size are jointly selected. Algorithm performance is compared with that of a(More)
In this paper, we propose a distributed beamforming scheme for the estimation of spatial fields (e.g. temperature, moisture) with wireless sensor networks. The pre-coding scheme allows for an over-the-air compressed representation of the correlated set of spatial observations, which are encoded in a number of consecutive sensor-to-gateway (GW)(More)
In this paper, we propose and analyze an opportunistic random access scheme suitable for distributed parameter estimation via wireless sensor networks (WSN). At the fusion center (FC), we assume that a Successive Interference Cancellation (SIC) scheme is available. Consequently, several sensor observations can be sent in parallel to the FC, this resulting(More)
