—The OFDM signals have a problem of high peak-to-average power ratio (PAPR). Hence, a large transmit-power backoff or amplitude clipping is required. The amplitude clipping cause...
— Performance comparison of multiuser OFDM-TDMA and OFDMA systems by considering physical and link cross-layer behavior is conducted in this work. We provide a new framework for ...
A major drawback of the Orthogonal Frequency Division Multiplex (OFDM) principle is the high dynamic range of the transmit signal. The transmit Power Amplifier (PA) and other ele...
