BER assessment of FFT-OFDM against WHT-OFDM over different fading channels [30]	In this research article, Haar transform is utilized to showcase the BER improvement in OFDM systems. However, the effects of other wavelet transform families such as symlet, coiflet, and reverse biorthogonal were not studied in this paper.
Comparative analysis of wavelet and OFDM-based systems [31]	In this paper, the appropriateness of constant envelope multicarrier modulation methodology, OFDM, and wavelet-based systems is deliberate. The prime idea of this paper is to do the assessment of wavelet-based and OFDSM-based systems by using BER vs. SNR performance metrics. In our present research, we have proposed an adaptive system which will select any of the optimum wavelets that will give us best PAPR and BER reduction.
On BER assessment of conventional- and wavelet-OFDM over AWGN channel [19]	Performance of OFDM system based on DFT and DWT transform is evaluated in this paper using the BER matric. Diverse modulation schemes (PSK and QAM) and levels (2, 4, 8, and 16) are being utilized to analyse the performance over AWGN channel for both DFT- and DWT-based OFDM system. However, in the present work, Rayleigh fading channel is explored for the assessment of the performance of conventional and proposed system model.
