Performance Analysis of Multilevel UEP Codes for Wavelet Video in W-CDMA over Fading Channels

Performance analysis of multilevel unequal error protection (UEP) codes with wavelet video compression for wideband code division multiple access (W-CDMA) over additive white Gaussian noise (AWGN) and Rayleigh fading channels are achieved and evaluated. Wavelets possess a dominant method and high quality for compressing video sequence. A spatially scalable video coding framework of MPEG2 in which motion correspondences between successive video frames is utilized in the wavelet transform domain. The proposed algorithms of the embedded zero-tree wavelet (EZW) coder and the two-dimensional wavelet packet transform (2-D WPT) are investigated. The wideband is carried with encoded data when transmitting through the AWGN and Rayleigh fading channels. Key-Words: Wideband Code Division Multiple Access, Multilevel Unequal Error Protection Codes, Embedded Zero-Tree Wavelet Transform, Two Dimensional Wavelet Packet Transform, Additive White Gaussian Noise, Rayleigh Fading Channel.
