  Abstract

In this paper, Multi-mode DWT-OFDM (Multi-mode Discrete Wavelet Transform Orthogonal Frequency Division Multiplexing) system that can improve spectral efficiency is designed and its performance is evaluated. Multi-mode DWT-OFDM system that can improve spectral efficiency by combining DWT-OFDM (Discrete Wavelet Transform Orthogonal Frequency Division Multiplexing) system and multi-mode DFT-OFDM (Multi-mode Discrete Fourier Transform Orthogonal Frequency Division Multiplexing) And compare it with OFDM (Orthogonal Frequency Division Multiplexing) system based on existing Fourier transform. Multi-mode DWT-OFDM system, which uses several wavelet functions and sends index bits to them, has more bit transmission capacity than the conventional DFT-OFDM system, and has the same BER (Bit Error Rate) performance The spectral efficiency is improved by about 11%.
