code errors

I'm confused by the 40th line of code in the ACO_OFDM.m:
receiveSymbol=awgn(IFFTOutput,2*snr,'measured');
Why the snr is multiplied by 2 rather than 4? As you know, the number of useful tones is lengthOfIfft/4 thus the useful power in an OFDM symbol is correspondingly a quarter of the total power, which is equivalent to multiply snr by 4 instead of 2.

I do not familiar with the awgn function of MATLAB.
A new version of ACO-OFDM has been upload; I hope this will help you.
