Universal-filtered multi-carrier (UFMC) waveform
is considered as a potential candidate for next generation wireless
systems due to its robustness against inter-carrier interference
(ICI) and the low latency required in 5G systems. In this paper, a
pulse shaping approaches in UFMC technique is studied to reduce
the spectral leakage into nearby sub-bands. The performance of
various types of window functions such as Chebychev, Hamming,
Hanning and Blackman with UFMC are compared. This leads
to different coefficients and attenuation shapes, that enabled
to choose the proper window function. Finally, a new selective
mapping (SLM) peak to average power ratio (PAPR) reduction
technique is proposed to enhance the UFMC system performance.
Results show that the BER performance of UFMC with all
windows functions are the same. However, Blackman window
function has a higher attenuation for sidebands compared with
others.
