A comparative analysis of Bohman Windowing Performance for UFMC with Higher QAM Modulation

This paper presents a study on the performance of different windowing techniques for high-level quadrature amplitude modulation (QAM) in universal filtered multicarrier (UFMC) systems. The focus is on comparing the impact of different windowing types on bit error rate (BER) performance, peak-to-average power ratio (PAPR), and out-of-band emission (OOBE). The present study assesses the performance of the Bohman window in the context of QAM levels, namely 256QAM, 512QAM, and 1024QAM, under a signal-to-noise ratio (SNR) of 15 dB. The findings indicate that utilization of the Bohman window yields a 3.21% enhancement in BER performance, a 1.01% reduction in PAPR, and a decrease in OOBE by 62.46 dBW/Hz for the 1024QAM in contrast to conventional UFMC. At 20 dB SNR, the BER is still lower than the traditional by 1.16%, but PAPR remains unchanged.
