“…OFDM has very large number of subcarrier signals which carry data on parallel data stream. Consequently, each of these subcarriers is modulated with one of the common modulation techniques such as phase shift keying or quadrature amplitude modulation [4,5]. The principle of subcarriers (or sub-bands) in OFDM improves the performance of the system.…”

<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>

“…Wavelet OFDM is the challenging technique in multicarrier transmission scheme .recent years, the application of wavelet OFDM in the broadcasting system is keeping on increasing .many areas like hybrid power line communication [9], visible light communication [9],5G communication [10], [11], cognitive radio [12], Multicarrier CDMA [13], UWB system, cognitive UWB [14], and satellite communication uses wavelet OFDM. In conventional FFT there is a requirement cyclic prefix insertion to reduce the intersymbol interference, which consumes large bandwidth.…”

In Digital Video broadcasting there are two types of information namely global and local content. Broadcasting both information using multifrequency network requires large spectrum. To overcome that single frequency network is incorporated.Inorder to transmit both the information in a single frequency network, a novel technique, namely selected subcarrier method of Digital Video Broadcasting is proposed. This technique is well suited in a scenario where the transmission of two different information is targeted over the entire globe at the same time. This methodology proficiently handles the concept of Orthogonality principles among the OFDM subcarrier. In this technique certain dedicated subcarrier is used for transmission of Local content in the network.Also, wavelet-based OFDM has been proposed, which outperforms the existing Fourier based OFDM

“…In [12], orthogonal frequency division multiple access (OFDMA) was explored for VLC due to its high spectrum utilization efficiency and potentially high transmission data rate. A power line communication-VLC hybrid high data rate transmission approach with discrete wavelet transform (DWT)-based OFDM was designed and proposed for 5G communication systems in [13]. OFDM and multiple light-emitting diodes (LEDs) with spatial summing was developed to reduce the high peak-to-average power ratio (PAPR) in [14], OFDM-interleave division multiple access (IDMA) was applied in [15] to uplink a multiuser visible light communication system to solve inter-symbol interference (ISI) and multiple access interference (MAI) problems.…”
