Here is an example on how to transmit a sinusoid from your speakers (try different values for the parameters fc and SecSound).
fc=1000; fs=44100; SecSound = 2; rS = cos(2*pi*fc.*[0:1/fs:SecSound]); y_test=audioplayer(rS,fs); playblocking(y_test);
Here is an example on how to listen a signal with a microphone for .
recorder=audiorecorder(fs,16,1); recordblocking(recorder,SecSound); R=getaudiodata(recorder); % R should be a vector with the listened signal
To make sure you received something that makes sense you can play R using
y_test=audioplayer(R,fs); playblocking(y_test);

Below you can find the timeslots in which you can access room E:4123 to work on the PIWC course until Christmas apart from the help sessions:
Mondays - 13-17
Thursdays- 13-17
Fridays - 13-15
Moreover, I changed the room of the help session on Wednesdays 15-17 to E:4123.

Based on the results of the poll, it appears that the best time slots are on Wednesdays and Fridays (there is at least 1 day in between help sessions which is good for you). Thus, here is the schedule until Christmas:
Wednesdays 15.00-17.00 @ E:4119 E:4123
Fridays 15.00-17.00 @ E:4123
Note that the rooms are different. The first help session will be on the 16th of Nov. here I will give a demonstration of a (hopefully) working project. In the meantime, you can start working by implementing the OFDM transmitter (you already have the receiver from the last task).

As Fredrik mentioned in the lecture, here is a Doodle poll for possible time slots for the 2 weekly help sessions: http://doodle.com/poll/s5s7it3q4mf64cxy
Please tick every time slot that you can attend (not only the 2 slots that fits you better). I will choose the 2 slots that most people can attend provided that everyone can attend to at least 1 help session. I will let you know the answer by Friday night, and also what are the lab. rooms.
Note that the doodle timeslot are only addressing the week from 14th to 18th of November, but these time slots are valid starting from that week until Christmas (for the whole study period).
Comments: It is not mandatory to attend to any help session. In the first help session I will make a short DEMO of what the project should look like at the end.
