Software-Defined Radio for Engineers, by Travis F. Collins, Robin Getz, Di Pu, and Alexander M. Wyglinski, 2018, ISBN-13: 978-1-63081-457-1. We will use this book in the second half of the course, and it covers many of the aspects in the first half as well.
There is a free pdf of the book available, see http://www.analog.com/en/education/education-library/software-defined-radio-for-engineers.html.
Hints, part 1
For converting the ASCII code, you may get help from the following matlab code:
For Task III, you can use the following code for designing the digital filter:
FilteredSignal = filter(B,A,SignalToFilter);
(B,A) need to be selected properly by yourself.
Hints, part 2
For transmitting the audio signal, you can use the following code:
tx = audioplayer(DataTrans,SamplingFrequency);
For recording the audio signal, you can directly use build in function audiorecorder, for example:
