This paper presents the design of a RF pulse width (PW) modulator for switched-mode power amplification of varying envelope signals such as CDMA or OFDM. The low level of spectral regrow in RF PW modulated signal is ensured by RF pulse swallowing pre

In this study, we experimentally investigated the adjacent channel leakage ratio (ACLR) performance degradation for the output signal of the RF HPA equipped with the adaptive linearization caused by RoF links placed in both direct and feedback paths

In order to provide broadband communication, the signal bandwidth has continuously increased in existing 4G and will keep increasing in upcoming 5G communication systems. Therefore, as the bandwidth of the transmitting signal increases, memory effect

One of the major drawbacks of multicarrier transmission is the high peak-to-average power ratio (PAPR) of the transmit signal. In this paper, we propose a PAPR reduction technique for mixed-modulation multicarrier transmission into subcarriers. We sh
