Laborationer
There will be two help sessions per week. These will be held in E:4123.
These help sessions do not have any formal program. Joao (or I) will be in the lab to assist you with any problems that you may have with the project tasks.
The first session, however, does have a formal program (click here), but it is not mandatory to finish it. However, if you go through it, you will essentially solve task 1 of the project, so it is time well spent. The first session is on Friday 5/9, 13-17 in E:4123 and E:4121.
Decided time-slots for helping sessions on E:4121:
Tuesdays from 13:00 to 15:00
Fridays from 13:00 to 15:00
Please note: Friday 2014-09-12 the help session will take place from 15:00 to 17:00 at E:4115.
This matlab code converts a sequence of bits (u) into plain text using ASCII
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
Important message for Task2:
the symbol time is 2.2676 ms and not 2.3 ms!
You might want to use these 8-th order lowpass Butterworth filter ( butter(...) in Matlab ) coeficients with normalized cut-off frequency Wn=0.05 if you cant access to Matlab Signal Processing toolbox.
