Abstract

Additive white noise AWGN Binary codes Bit error rate Fading Intelligent transportation systems Power engineering computing Quadrature amplitude modulation Reflective binary codes Signal to noise ratio
When the number of bits per symbol is odd, the peak and average power of transmission can be reduced by using cross quadrature amplitude modulations (QAMs) instead of rectangular QAMs. Since perfect Gray coding is not possible for cross QAMs, using Smith-style Gray coding, we derive in this paper the exact bit error rate (BER) for the cross 32-QAM constellation over additive white Gaussian noise (AWGN) and Rayleigh fading channels.
