In previous works on simultaneous wireless information and power transfer (SWIPT) multiple-input single-output (MISO) system with multiple users, beamforming requires all the transmitters know the channel state information (CSI) of the whole system. We relax it so that it is a practical assumption: Each transmitter only knows its own CSI to all the receivers, combined with individual power constraints...
Localization is one of the most challenging and important issues in wireless sensor networks (WSNs), especially if cost-effective approaches are demanded. Range estimation is essential in many sensor network localization algorithms. Although wireless sensor systems usually have available received signal strength indication (RSSI) reading, but RSSI is susceptible to external influences, performances...
Frequency-domain equalization (FDE) is an effective technique that exhibits the property of relatively low complexity growth with increasing the number of symbols of dispersion in multipath propagation environments for broadband wireless communications compared with the conventional time-domain equalization (TDE). However in practical broadband wireless communications, there exists not only multipath...
