Abstract
Four signal-to-noise ratio (SNR) estimators for quartenary phase-shift keyi ng (QPSK)-like signaling are proposed and examined. Two are based on receiv er statistics directly related to SNR while two others are based on receive r statistics inversely related to SNR. The results show that the estimators based on the inverse of SNR perform better than the estimators based on SN R.
