SINR Calculation by C++ ?

I am trying to calculate signal to interference noise ratio for a source to destination in different sub-channel base on shannon capacity formula. Does anyone know the formula for differentiating the sub-channels? can anyone please give me a reference through this calculation?

thanks :)

I'm not sure why you can't just use the bandwidth and capacity of each subchannel, when plugging numbers into Shannon's equation. And then you should notice that assuming all of the subchannels as one wider channel (with correspondingly higher capacity of course) will give the same results of SNR threshold value.

This really does work. Reason being, Shannon's equation is modulation-agnostic. Channel bandwidth goes hand in hand with capacity, for any given SNR threshold.
