I recently got the WBX daughterboard and updated GNURadio after a year or two of hiatus. I really like the WBX so far, and have some ideas for receivers, like an ACARS decoder that decodes multiple

Articles I read say that a 10MSPS rate gives better performance that a 8MSPS rate. I used the 8MSPS rate and still got good performance. The oversampling is used in determining if the pulse is valid

Thinking over the design of the Mode-S/ADS-B receiver I have a possible improvement. It changes the serial method of demodulation to a parallel block method. Mode-S/ADS-B is a smaller bandwidth signa
