Issues surrounding wireless communications have arisen as a result of an increase in popularity and usability. The complexity of modulating signals onto carriers while optimizing bandwidth usage has always been considered to be one of the most significant challenges. The discovery of the wavelet transform has opened up a number of potential applications from image compression to watermarking and encryption. In the past, work has been done to investigate the potential of using wavelet transforms within the communication space. This paper will further investigate a recently proposed, innovative, modulation technique, Orthogonal Wavelet Division Multiplex, which utilizes the wavelet transform opening a new avenue for an alternative modulation scheme with some interesting potential characteristics. |
