We propose a wireless power transfer (WPT) based underlay spectrum sharing scheme, where a primary user (PU) needs to harvest wireless energy from an access point (AP) and then transmit its data to AP using the harvested energy. In the same area, a secondary transmitter (ST) intends to communicate with a secondary receiver (SR). The secondary data can be transmitted along with the WPT, which can on...
This paper investigates multi-user scheduling in a full-duplex (FD) wireless-powered communication network, consisting of multiple energy harvesting (EH) source nodes (SNs) and one FD hybrid access point (HAP). All SNs have no embedded energy supply and thus need to perform EH before transmitting their data to the HAP. Thanks to the FD capability, the HAP simultaneously receives data from the scheduled...
To coordinate the various access technologies in the 4G-communication system, intelligent vertical handoff algorithms are required. This paper mainly deals with a novel vertical handoff decision algorithm based on fuzzy logic with the aid of grey theory and dynamic weights adaptation. The grey prediction algorithm (GPA) takes 4 sampled received signal strengths as input parameters, and calculates...
In this investigation, two probabilistic latent semantic analyses (PLSA)-based approaches are proposed for use in speaker verification systems to reduce the number of parameters required by prosodic speaker models to (1) estimate reliably speakers' bi-gram models and to (2) reduce the amount of required training and test data. The basic concept is to (1) adopt PLSA to smooth the underlying n-gram-based...
