64qam coomunication system and

I want to design a 64 qam communication system in matlab. Does anyone has the complete code . ??
What do i do?/ where do i begin ?? Pls help me out here ? Its a project due very soon .
I want separate codes for 64 qam baseband modulator and demodulator

try using the functions in the matlab. I'm afraid there aren't any codes out there which I've came across using 64qam modulation scheme yet.


modulation = modem.qammod('M', P, 'SymbolOrder', 'Gray');

demodulation = modem.qamdemod(modulation);

U can use following Commands for 64 qam

data = randint(1,100,64);
mod_data = qammod(data,64);
scatterplot(mod_data)

do you mean the data mapping in the constellation diagram?

do you mean the modulation and demodulation with out need to its construction and how does it work? if so , the above answers are both correct but if no, you will need to follow the general rule for constellation construction and program it in matlab. see this link http://www.dspdesignline.com/207601...13AYQSNDLQCKHSCJUNN2JVN?printableArticle=true
