High peak to average power ration (PAPR) leads to signal distortion and limit the high power amplifier (HPA) performance. Constellation extension scheme (CES) is an effective method to reduce the PAPR. CES generates candidate sequences by extend the constellation points and chooses one of candidate sequence with minimum PAPR as the transmitted sequence. Using Asterisk 16QAM modulation has better performance...
Single-carrier frequency division multiple access (SC-FDMA) systems are currently being replaced with the long-term evolution (LTE) scheme as the main uplink transmission technique. Compared with orthogonal frequency division multiple access (OFDMA) systems, SC-FDMA systems exhibit lower peak-to-average power ratio (PAPR). However, modulation and pulse-shaping techniques vary among systems, and PAPR...
