| Summary: | High Peak to Average Power Ratio (PAPR) is a
critical issue in multicarrier communication systems using
Orthogonal Frequency Division Multiplexing (OFDM), as in the Second
Generation Terrestrial Digital Video Broadcasting (DVB-T2)
system. This problem can result in large performance
degradation due to the nonlinearity of the High Power
Amplifier (HPA) or in its low power efficiency. In this paper,
we evaluate the performance of different Tone Reservation-based techniques for PAPR reduction in DVB-T2 context.
Also, we propose an iterative TR-based technique called “One
Kernel One Peak” (OKOP). Simulation results and performance
comparison of these techniques in terms of gain in PAPR
reduction, mean power variation, and complexity will be given. Finally, we describe the implementation of a PAPR reduction
algorithm in the DVB-T2 modulator. |
