“…The purpose of overlapping of subcarriers in OFDM is to obtain maximum spectral efficiency. Although these subcarriers are orthogonal to one another but overlapping adjacent channels can interfere with one another [4,7]. As a result, the subcarriers have the ability to overlap without interfering and accordingly provide the maximum spectral efficiency.…”

“…The concept of modulation and multiplexing system (OFDM) is transmitting data in parallel at the same time through multiple carriers using different frequency bands. These carriers are Fourier complex exponentials in classic OFDM, in other words they are Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT), which are used to map symbols to plurality of subcarriers [1]. In fact, any set of orthogonal and normalized functions can be used as carriers of OFDM system such as wavelet.…”

<p>Nowadays, emerging wireless networks scenarios such as the proposed systems for 5G is discussed widely with diverse requirements. Orthogonal Frequency Division Multiplexing (OFDM) is a conservative proposal which is used to build 5G WOFDM system (Wavelet OFDM system). The simulation of the system is initialized with BPSK then with QAM and 64-QAM the system is improved by increasing the number of levels of Discrete Wavelet Transform to five levels and finally compared with original system to prove that the it is convenient for 5G Wireless networks.</p>
