Reduced oob emission and PAPR using partial-OSLM technique in 5G UFMC systems

الملخص EN

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.
