On the PAPR of the LTE-Based 5G Terrestrial Broadcast System

Peak-to-Average-Power-Ratio (PAPR) is a common issue in multicarrier communication systems like the Orthogonal Frequency Division Multiplexing (OFDM) system. Since the amplitude and phase of signals on each subcarrier are independent, the peak power of the superimposed signal may be tremendous. High...

Description
Summary:Peak-to-Average-Power-Ratio (PAPR) is a common issue in multicarrier communication systems like the Orthogonal Frequency Division Multiplexing (OFDM) system. Since the amplitude and phase of signals on each subcarrier are independent, the peak power of the superimposed signal may be tremendous. High PAPR would seriously reduce the amplification efficiency of high-power amplifiers (HPA) and the accuracy of Digital-to-Analog Converters (DAC). LTE-Based 5G Terrestrial Broadcast is the latest broadcasting system based on mobile communication and aims at providing broadcasting services to ubiquitous terminals. High PAPR is a non-negligible problem restricting the application of this system and has not been adequately solved. This paper studies the PAPR problem in LTE-Based 5G Terrestrial Broadcast and introduce the Tone Reservation (TR)-based PAPR reduction algorithm to this system. A modification is then proposed on the TR algorithm to better adapt the LTE-based broadcast system, and the impact of the TR algorithm on this system is analyzed. Simulation shows that the TR algorithm can well address the PAPR problem in LTE-Based 5G Terrestrial Broadcast and can be used as a candidate technique.
