TL;DR: A multi-standard simulator has been developed to validate the architectural and design choices in terms of error rates at bit or packet level and the ideas behind the key RF blocks and some details of circuit implementation are described.

TL;DR: A complete experimental data set of received signal strength indicator measurements collected in different indoor and outdoor environments using LoRa radios is presented and simple and power efficient localization algorithms are applied on the obtained data set.

TL;DR: A Kalman-based formulation for hybrid analog/digital precoding in multi-user environment is proposed, and an analytical expression of the error between the transmitted and estimated data is formulated, so that the Kalman algorithm at the base station does not require information on the estimated data at the mobile stations, and instead, relies only on the precoding/combining matrix.

TL;DR: This paper illustrates an implementation of a global system for mobile communications (GSM) receiver in which channel equalization and demodulation are realized by means of the nearest neighbor (NN) classifier algorithm.

TL;DR: A novel algorithm is proposed to improve the RSSI ranging output by a Wiener-based method that minimizes the distance logarithm error, instead of interpolating the free-space path loss model as in common solutions, resulting in a more precise ranging and positioning.
