Here there will be news and some hints for the project.
Help sessions
The help sessions will take place Mondays and Tuesdays 15.15-16 (max). If you have anything to discuss, make sure to be there at 15.15 as Guoda and MinKeun will leave after a short while if there are not any issues to discuss.
During HT2, the same schedule will be used for the help sessions.

Recommended reading
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
For converting the ASCII code, you may get help from the following matlab code:
wh=2.^[6:-1:0];
m=char(TransmittedBits(1:7)*wh');
for l=2:floor(length(TransmittedBits)/7),
m=[m char(TransmittedBits(7*(l-1)+1:7*l)*wh')];
end
m

For Task III, you can use the following code for designing the digital filter:
FilteredSignal = filter(B,A,SignalToFilter);
(B,A) need to be checked by yourself.

Project description, HT2, part one
The project description for part one is now available: Projectdescription_Part1_HT2_2018
Hints:
Audio Part:
For transmitting the audio signal, you can directly use the following code:
tx = audioplayer(DataTrans,SamplingFrequency);
playblocking(tx);
For recording the audio signal, you can directly use build in function audiorecorder, for example:
recorder=audiorecorder(fs,16,1);
recordblocking(recorder,SecSound);
R=getaudiodata(recorder);
