Software-defined radio (SDR) is a radio communication. HackRF One from Great Scott Gadgets is a SDR (Software Defined Radio) peripheral capable of receiving and transmitting radio signals between the frequencies of 1 MHz and 6 GHz, including most devices operating with: Bluetooth, FM radio, near-field communication (NFC), cellular technology/smart phones, WiFi, GPS and IT infrastructures. The B210/B200 transceiver is largely based on the AD9361 IC, which can tune from 70 MHz to 6 GHz, based on available information from the manufacturer. The HackRF can tune about 20 MHz lower than the B210/B200, but both devices can tune as high as 6 GHz. The HackRF and the USRP B210 can tune to a huge amount of the radio spectrum. I bought a HackRF One because I wanted to try other things, but it was an impulsive buy A HackRF One GNU Radio Companion FM Tuner with Band Visualization GUI One box for everything is better: Nooelec's R820T2 and Ham-It-Up in a metal case would be my choice if I went into a warzone, but needs one more cable and one more USB port 1, and your.

Burg, “An Open-Source LoRa Physical Layer Prototype on GNU Radio” Verification of explicit header checksum.Spreading factors: 7-12 (without reduce rate mode).Sending and receiving LoRa packets between USRP-USRP and USRP-commercial LoRa transceiver (tested for Adafruit Feather 32u4 RFM95 and dragino LoRa/GPS HAT). The implementation can be used for fully end-to-end experimental performance results of a LoRa SDR receiver at low SNRs. The demodulation block follows, along with the Gray demapping block, the deinterleaving block, the Hamming decoder block and the dewhitening block, as well as a CRC block. On the receiver side there is the packet synchronization block, which performs all the necessary tasks needed for the synchronization, such as the necessary STO and CFO estimation and correction. In the Tx chain, the implementation contains all the main blocks of the LoRa transceiver: the header- and the CRC-insertion blocks, the whitening block, the Hamming encoder block, the interleaver block, the Gray mapping block, and the modulation block. In the GNU Radio implementation of the LoRa Tx and Rx chains the user can choose all the parameters of the transmission, such as the spreading factor, the coding rate, the bandwidth, the sync word, the presence of an explicit header and CRC. How wide a swath depends upon the hardware’s RF front end, while the number and types of signals that can be. This work has been conducted at the Telecommunication Circuits Laboratory, EPFL. From military and aerospace to hobbyists, the promise of software-defined radio (SDR) is that with one piece of hardware, users can capture, demodulate, and access RF signals across a wide swath of radio frequencies. The transceiver is available as a module for GNU Radio 3.8. This is the fully-functional GNU Radio software-defined radio (SDR) implementation of a LoRa transceiver with all the necessary receiver components to operate correctly even at very low SNRs.
