- W2913506967 abstract "Generalized Frequency Division Multiplexing (GFDM) has been regarded as one of the most promising multicarrier modulation schemes for the upcoming fifth generation (5G) mobile communication system. However, similar to other multicarrier schemes, GFDM still suffers from the problem of high Peak-to-Average Power Ratio (PAPR). To reduce the PAPR effectively, we propose an efficient nonlinear companding scheme to transform the statistics of GFDM signals into a half-sine distribution form along with remaining an unchanged average signal power in GFDM blocks. Additionally, a new iterative reception method for the receiver of GFDM is also proposed to obtain a better bit error rate (BER) performance. This scheme can achieve a significant reduction in PAPR and an improved BER performance simultaneously. By properly adjusting system parameters, more design flexibility in companding form and an effective trade-off between PAPR reduction and BER performance can be obtained. Compared with existing solutions for PAPR reduction in GFDM, simulation results illustrate that the proposed technique can achieve a better overall performance in terms of PAPR reduction and BER performance." @default.
