IEEE transactions on communications, 2006•ieeexplore.ieee.orgThe exact closed-form expression for the bit-error rate (BER) of rectangular quadrature
amplitude modulation (QAM) is given. The presented formula is independent of the bit
mapping and it is thus particularly useful in the design and analysis of modulation schemes
employing non-Gray mapping. Compared with the so-called expurgated bound and the
union bound, our expression is shown to accurately predict the BER in the low signal-to-
noise ratio range where the bounding techniques fail.
