Digital beacon receiver for ionospheric TEC measurement developed with GNU Radio

Development of a Leo Beacon Receiver System for Tec Measurement and Simulation of an Orthogonal Carrier Spread Spectrum System

The ground-based reception of radio beacon signals transmitted from LEOS is a historical method to measure the total electron content (TEC) of the ionosphere. Observations of this kind were initiated right from the beginning of the space era as reported by Aitchison and Weekes [1959] and Garriott and Little [1960]. The principle of the experiment is based on the frequency dependence of the refr...

A LTE Receiver Framework Implementation in GNU Radio

We present an open source LTE receiver framework. Using GNU Radio‘s block-based signal processing capabilities, various LTE baseband specific functionality has been implemented in dedicated easily reconfigurable blocks. These can be used to decode and analyze arbitrary channels in the LTE downlink signal. As an example we decode the Master Information Block (MIB) transmitted on the Broadcast Ch...

Typical Ka band Satellite Beacon Receiver Design for Propagation Experimentation

This paper presents the design and simulation of a typical Ka band satellite beacon receiver for propagation experimentation. Using satellite beacon signal as a reference signal in satellite wave propagation study, is one of the most important methods. Satellite beacons are frequently available for pointing large antennas, but such signals can be used for measuring the effect of natural phenome...

Research on Key Digital Modulation Techniques Using Gnu Radio

Neural Network – based Digital Receiver for Radio Communications

This paper proposes a novel digital receiver, based on a multilayer perceptron neural network architecture, which works in a radio communications environment. Training is carried out by the variable learning rate back-propagation algorithm with momentum in a supervised manner and a batch training mode. We present computer simulation results comparing the performance of this receiver against the...
