We consider a distributed detection problem over fading multiple-access channels. Sensors observe a phenomenon and transmit their observations to a fusion center using the amplify-and-forward scheme. The fusion center has multiple antennas and uses the transmissions from the sensors to run a detection algorithm. The channels are Ricean fading, and the sensors have no channel information. The performance...
In this paper, we study distributed detection in ultrawideband (UWB) wireless sensor networks (WSNs) over frequency selective channels. Several schemes with different requirements on channel state information (CSI) are proposed, analyzed, and compared. We study the error exponent and asymptotic optimality for these schemes under different energy, and time-bandwidth product requirements. Our study...
