sdr_receiver_dvb_t2

Author: Oleg Malyutin Email: oleg.radioprograms@gmail.com

This is a Software Defined Radio(SDR) project implementing a DVB-T2 receiver.

The project was created using the Qt5 framework. To build the project, you need to install the library FFTW3: http://www.fftw.org

Supported devices:

1. SdrPlay (need to install API/HW driver – V2.(but not V3.) from https://www.sdrplay.com)
2. AirSpy
3. PlutoSDR
4. HackRF One
5. USRP B200 mini

For windows and PlutoSDR(windows) need libusb-1.0 branch: https://github.com/Novakov/libusb/tree/winusb-lazy-create-file

Received DVB-T2 signal parameters:

1. SISO and one RT-TX
2. 8MHz 16K or 32K only (32K tested)
3. Output Transport Stream(TS) (HEM mode tested)

Not supported:

1. FEF part
2. T2-Lite

Tested configurations: OS: Linux Mint 22 Wilma 64-bit. Windows 10 22H2 Processor: Intel© Core™ i5-8600 CPU @ 3.10GHz × 6 To view the video signal, a VLC player v2.x (not v.3x) with udp://@:7654 parameters was used (URL)

Note: Shifting (rotating) the antenna by a few cm can improve reception. Move with a pause - synchronization takes a few seconds. You can observe the quality of reception by the shape of the P1 symbol.
