책소개

The new generation of wireless communication systems has adopted dierent
waveforms. The universal filtered multicarrier is one of the adopted candidates
that has symmetry with various numerology designs. However, the high peak to
average power ratio is one of the major limitations faced by universal filter
multicarrier (UFMC) designers. Moreover, recent studies utilize cubic metric along
with the peak to average power ratio (PAPR) to show the power back-oeect of the
signal in which the PAPR metric identifies the maximum peak and the cubic metric
(CM) identifies the Out of Band emission and In-Band distortion. Most of the
current solutions, such as amplitude clipping, tone reservation, and active
constellation extension, decrease the PAPR but cause degradation to the bit error
rate. Selected mapping is one of the promising techniques that is recently used to
solve the PAPR and CM problems without causing bit error rate (BER) degradation.
In this paper, the selected mapping (SLM) is integrated with UFMC to reduce the
PAPR and CM without aecting the BER of 5G networks. The SLM-UFMC solution
model is simulated by MATLAB and the results show that the SLM-UFMC model
presents better PAPR and CM performance without BER degradation. The PAPR
has been decreased to 1.5 dB with respect to eight-phase rotation vectors and the
CM decreased to 1.25 dB compared to the conventional UFMC.
