Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: The signal constellation of 60 GHz millimeter wave (mmWave) communications is distorted by por amplifier (PA) nonlinearity seriously and the bit error rate (BER) performance declines, due to the huge bandwidth and high equivalent isotropic radiated por (EIRP), especially for quadrature amplitude modulation (QAM) signals.  aims at non-data-aided (NDA) distorted constellation (DC) estimation and demodulation to deal with PA nonlinearity. An estimation algorithm of expectation-maximization (EM) is proposed and the corresponding Cramer-Rao lor bounds (CRLBs) are calculated, then the estimated DC is used as reference for demodulation. Simulation results indicate that the means of the estimation results are unbiased and the mean square errors (MSEs) reach the CRLBs under easy requirements on signal-to-noise ratio (SNR) and output por back-off (OBO). Additionally, with PA nonlinearity, the BER performance of the presented DC demodulation is close to that of the ideal PA case, and much superior to that of the traditional standard constellation (SC) demodulation.
