A uniform random number generator is used to generate the binary information sequence from the binary data source. The sequence of '0's and '1's is mapped into sequence of +E and E where E represents the signal energy. E may be normalized to unity The Gaussian noise generator is used to generate the sequence of '0' mean and variance dcDo2 Gaussian random numbers.

This article consists of a brief discussion of the energy density over time or frequency that is obtained with the wavelet transform. Also an efficient algorithm is suggested to calculate the continuous transform with the Morlet wavelet. The energy values of the Wavelet transform are compared with the power spectrum of the Fourier transform.
