New methods of windowing for reducing the out of band emission with low complexity in the 5G waveform
Published 2022“…Thus, the present study contributed in three new methods in the time domain, namely, Kaiser Hankel subband Window (KHW), hybrid window group subcarrier-windowing (HWG subcarrier windowing), and Convolution New Window type-windowing (CNW windowing) to suppress the value of OOBE in F-OFDM and UFMC and improve Power Spectral Density (PSD) without degradation of Bit Error Rate (BER) in the system. On the other hand, two methods were proposed in the frequency domain to decrease the OOBE while maintaining a low computational complexity, namely, Array window subcarrier windowing (AWsubcarrer-windowing) and the Half subcarrier edge windowing (HSE-windowing). …”
