Analysis of DVB-T system using OWDM with various wavelet families

Orthogonal Frequency Division Multiplexing system used in number of communication systems. It is a powerful technique that uses an IFFT at the transmitter to modulate a high bit error rate signal onto a number of carriers. But it faced one problem that is inherently inflexible and requires a complex IFFT core. To overcome this problem a new DVB-T system is designed that utilizes the flexible nature of Discrete Wavelet Transform by using OWDM in instead of OFDM. As OWDM has low computational complexity and increased flexibility so it utilizes the resources in much better way. In OWDM, various mother wavelets can be used to improve the flexibility.
