Performance Analysis of Wideband MC-CDMA for Wavelet Video with Multilevel UEP Codes over Fading Channels
نویسندگان
چکیده
Performance analysis of multilevel unequal error protection (UEP) codes with wavelet video compression for wideband multicarrier code division multiple access (MC-CDMA) and Rake receivers 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 introduced system of wideband MC-CDMA and Rake receivers is operated for multipath problems. Each Rake receiver is provided for each carrier of MC-CDMA and each level of UEP codes. The wideband is carried with encoded data when transmitting through the AWGN and Rayleigh fading channels. Key-Words: Multicarrier Code Division Multiple Access, Multilevel Unequal Error Protection Codes, Rake Receiver, Embedded Zero-Tree Wavelet Transform, Two Dimensional Wavelet Packet Transform, Additive White Gaussian Noise, Rayleigh Fading Channel.
