Abstract: In this paper we consider the problem of faded wireless image and video transmission schemes under energy transmission constraints. An example of such a constrained system experiencing Rayleigh fading is Code Division Multiple Access (CDMA) where power control is used. We imposed on the average energy transmitted per an image or image sequence. A computationally inexpensive analytic mean square error (MSE) distortion rate (D-R) estimator for progressive wavelet coders which generates an exact distortion rate (D-R) function for 2-D and 3-D SPIHT algorithm is utilized from our previous research. Using the D-R function, the expected mean square error(MSE) at the receiver is minimized by optimally assigning the energy and parity allocation per each transmission block among the packets. A gain of 1.09 dB relative to optimal equal error protection (EEP) is obtained by varying both energy and parity among the transmission blocks. The results can be used to to increase image and video quality in CDMA systems.
