In this paper, four levels of analysis and synthesis filter banks are proposed to create, coefficients for a Continuous Wavelet Transform (CWT), a Discrete Wavelet Transform (DWT), and an Inverse, Discrete Wavelet Transform (IDWT). The main property of these wavelet transform schemes is their ability to construct the transmitted signal across a log-normal fading channel over Additive, White Gaussian Noise (AWGN). There are many applications of wavelet transforms in wireless communication systems, and the authors chose the design of rake receivers as a major application to mitigate interferences and reduce the noise.
