last two days were the most tiring days of my life
tired and exhausted
not physically but mentally
all because of one presentation that costs 15 percent in my grade
it was communication system
and it requires us to do a project
and then present the results that we simulated
it's about a QPSK modulator
for those who don't know about it, click
herewe need to simulate the modulator in MATLAB
FYI, MATLAB is a mathematical analysis program for simulation and result generation
one thing about this project is that it is brand new in this course
which means, our senior haven't done this before
which means, no previous samples to refer
which means, no answers to copy
which means, we need to figure it out ourselves
which means, it'll be a hard struggle before we can get the correct stuffs
we kick started the project a few weeks before the deadline
that time, we're thinking of using SIMULINK, a feature in MATLAB
for about one week of thinking, testing, consulting lecturer and coordinator
we got nothing
then we shifted our focus to solve using coding
which was the original instruction for the project
(because my lecturer allows SIMULINK
We tried to take the easy way but failed)
after scanning through the web
i found no solution
the same with my partner
but then some fella comes out telling my partner he got the program but cant generate the correct grpah
we got the program from him
it's just one of the samples i found and it's wrong
another week went by with no progress
a few days before submitting our report
my group member found another source of solution
but in the end we found out it was fraud
the so called 'smart guy' just renamed the file
from 'QPSK_TX.m' to 'QPSKkclimultimateEDITION.m'
what a blowoff
i just think that he was simply 'too smart'
and he 'totally' understood the codes
just so to put his name and the word 'ultimate edition'
as the file name
so that anyone getting the answer will be his honor
in the end, he succeeded
almost 90 percent of the groups used the same code
and ended up rejected by the lecturer
bravo~ BRAVO!
nothing comes without effort
it's true
they receive nothing by doing nothing
back to my group
we still have nothing
so, we combined with another group to discuss
last two days
we found a bunch of codes that we can use
we spent the whole night trying to integrate it into the 'ultimate edition' codes
discussing and retrying
trying to understand the original codes at the same time
results won't appear the moment we start working on it
we got nothing but a bunch of errors and warnings
my MATLAB program gave up on me at 2am
it simply wont simulate anymore
forcing me to reinstall it
uninstalling took me a mere 15mins
reinstalling costs me one hour!!
but after reinstalling, the problem persists
i was very frustrated and disappointed
then my role in the discussion group changed
since i cant simulate
i change the codes and send to the others
and they send back the results after simulation
we have me, my partner CH and KV and Jo from another group
four brains can't beat a few lines of codes
we gave up at 5am and went to sleep
the next day i overslept but manage to arrive for the 8am class
after the 10am class, KV told us that a guy manage to do it
and he got the codes with his group mate
my 8 hours of effort just went to waste within 5mins
there goes my sleep also
Jo even made coffee to stay up to do the codes
after obtaining the codes
we spent another 3 hours trying to modify it
we also tried to integrate his codes into our
failed in the end too
we gave up and continued to complete our report with the results we get
at 3pm
KV's group went on to presentation after printing the report
while i finish up my lunch
the lecturer has the same speech as she did to previous groups
'i know you get the codes from the internet'
'i recognize it as soon as i see it'
'what does this code mean?'
'what does this value represent?'
'how you get this result?'
'show me *this* show me *that*'
eavesdropping their presentation made me feel insecure with my report
KV's group came out being rejected
they sounded like giving up
but luckily we got all the tips from them
what the lecturer asked and what she want
so we spent another 2 hours modifying the codes and report again
CH left for class in the process and our presentation was delayed until 5pm
(it was supposed to be at 3.45pm till 4.00pm)
presentation was stressful when we messed up the code files
the lecturer was frustrated
i was frustrated
the codes were messy
soon, we manage to get pass those obstacles
all spent was worth it when the lecturer is satisfied with our presentation
and we can go home and get some rest
i slept at 7pm on friday
woke up to answer a call in the middle of it
don't know what time was that
the time i really wake up was after 10am this morning
i slept for 15 hours straight because of one presentation!
last time worked for two days straight was not that tiring either
(though i slept for 14 hours that time)
now i know that mental fatigue is far more serious than physical fatigue
for those out there..make sure you get enough of your sleep
and for those doing reports and presentations, good luck
