TL;DR: SCBT with MMSE-FDE (aided by SNR estimation), based on a simple signal-to-noise ratio (SNR) estimation method for single-carrier block transmission (SCBT) over multi-path fading channels is very promising for realizing data rates of multi-Gbps in wireless personal area network (WPAN).

TL;DR: These trials are to test a number of aspects of white space technology, including the white space device and geolocation database interactions, the validity of the channel availability/powers calculations by the database and associated interference effects on primary services.

TL;DR: It is found that the proposed STDMA scheme is capable of improving system throughput as much as 100% and the co-channel interference in a communication link has to be controlled at/below -15dB in order to achieve the optimum system throughput.

TL;DR: Dynamic changes that have recently been made possible to the physical characteristics of elements closer to the antenna, including the antenna itself, improve the vast repertoire of waveform, frequency, bandwidth, and other adaptations that might be achieved through a simple software and/or configuration update in an SDR.

TL;DR: In this paper, a wireless communication terminal enables connection with a plurality of base stations disposed in different positions, which includes a base station scanning unit 100 detecting and scanning a BS capable of communication at the current position of the WSN, a simultaneous detection base station recording unit 101 recording simultaneously detected base stations as simultaneous detection information in a storage unit, a connection candidate extraction unit 102 and a first communication unit 103 performing communication by connection with the extracted connection candidate BS.
