A Crystal-Less BLE Transmitter With Clock Recovery From GFSK-Modulated BLE Packets
IEEE Journal of Solid-State Circuits, 2021In this article, we present a crystal-less Bluetooth low-energy (BLE) transmitter using RF reference recovery directly from GFSK-modulated BLE packets. In order to achieve fast frequency calibration from modulated signals and reduce interference from other BLE users, the transceiver consists of a back-channel wake-up receiver, a clock-recovery receiver,

BLE Localization With Polarization Sensitive Array
IEEE Wireless Communications Letters, 2021This letter presents a design and implementation of a bluetooth low energy (BLE) localization scheme using polarization sensitive arrays, where both the direction and polarization information is explored for high-accuracy positioning. The signal frequency offset and channel mismatch error are mitigated by the proposed frequency compensation and array ...

Home Lighting controller based on BLE
2017 IEEE International Conference on Consumer Electronics (ICCE), 2017This work deals with an application of wireless communication technologies (BLE) to the creation of a Home Lighting Management System (HLMS). Our aim is to create a system based on BLE in order to implement an universal smart lighting controller which allows performing a remote lighting control system for in-home environments.

Targeted advertising using BLE beacon
2017 IEEE 6th Global Conference on Consumer Electronics (GCCE), 2017Although cameras are commonly used to achieve customer's attributes in the field of advertising, improving the precision of these consumer features just by imagery has been a great challenge. This paper proposes a new targeted advertising method experimentally accommodated to digital signage systems by using Bluetooth Low Energy (BLE) beacons.
