Balint's SDR Tutorials

Here is some content to get you started with SDR:

(This assumes you already have GNU Radio installed.)

• Python

• Learn some Python basics for use with GNU Radio and GRC (GNU Radio Companion)

• Labs 1 - 5 in GRC

  Also includes: helpful tips, 'asides' that attempt to demonstrate the nature of complex (IQ or quadrature) signals, explain in detail some important concepts when it comes to using SDRs in real apps, explain how GRC works and what all of the parameters for various blocks control.

  (An SDR is necessary for labs 4 & 5)

1. Creating and plotting a sine wave
2. Adding noise and viewing in the frequency domain
3. Outputting the sine wave to your sound card, as well as sampling from the sound card and plotting audio as a waterfall
4. Receiving Narrow- and Wide-band FM using an SDR, and decomposing the FM demodulator into its individual blocks
5. Transmitting your own Narrowband signal with an SDR
