One of modulation systems which offers bandwidth efficiency is Orthogonal Wavelet Division Multiplexing (OWDM) system. This paper deals with the performance evaluation of wavelet packet modulation for wireless digital communications in the presence of additive white Gaussian noise (AWGN) and frequency selective fading with Rayleigh distribution. The implementation of wavelet packet modulation with $M$ -ary phase shift keying (PSK), called as $M$ -ary PSK OWDM, is proposed to achieve high performance of modulation with bandwidth efficiency. As comparison, the performance of $M$ -ary PSK Orthogonal Frequency Division Multiplexing (OFDM) is also conducted in similar channel circumstances. The result shows the use of wavelet packet modulation could significantly improve bit error rate (BER) compared to $M$ -ary PSK OFDM system.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Additive White Gaussian noise,Bandwidth efficiency,Digital communications,M-ary phase shift keying,Orthogonal wavelet division multiplexing,Rayleigh distributions,Wavelet packet modulation,Wireless digital communications[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Additive White Gaussian Noise (AWGN),M -Ary phase shift keying (PSK),Orthogonal Wavelet Division Multiplexing (OWDM),Rayleigh fading,Wavelet packet modulation[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ISNCC.2019.8909167[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
