Orthogonal Time Frequency Space Modulation: Pilot Power Allocation and Nonlinear Power Amplifiers
Original language description
This paper deals with a pilot power allocation in the orthogonal time-frequency space (OTFS) modulation system. In our simulations, the pilot is used for a channel estimation. Subsequently, the channel effects are equalized via a deconvolution. It is shown that proper solution of the pilot power allocation problem has significant impact on the bit-error rates. We also show that the increase of the pilot power causes notable increase of the peak-to-average (PAPR) power ratio. In consequence, high PAPR is one of the limiting factors of the pilot power increase. Considering a non-linear power amplifier, high PAPR is demonstrated to limit the OTFS bit-error rate performance.
