    • Bit Interleaved Space-Time Codes 

      Muharemovic, Tarik; Gatherer, Alan; Ebel, Will; Srihosour, Srinath; Hocevar , Dale; Huang, Everest (2001-09-20)
      We develop a new construction criterion for BSPK space-time codes which simultaneously reflects both "coding" and "diversity" advantage. Furthermore, we propose a new method of improving the performance of space-time ...
    • Improving Performance of a Space-Time Turbo Code in a Rayleigh Faded Channel 

      Huang, Everest; Gatherer, Alan; Muharemovic, Tarik; Hocevar , Dale (2001-10-20)
      Starting with an ordinary parallel concatenated turbo encoder in a block fading Rayleigh channel, we introduce bit-interleaving of the outputs, not for time diversity, but to increase the coding gain. We develop a guideline ...
    • Space-Time Codes with Bit Interleaving 

      Muharemovic, Tarik; Gatherer, Alan; Ebel, Will; Srihosour, Srinath; Hocevar , Dale; Huang, Everest (2001-11-20)
      We develop a new construction criterioin for BSPK space-time codes. Based on this criterion, we propose a new method of improving the performance of space-time codes, namely bit interleaving. Then, we provide a computationally ...
    • A Wavelet-Based Statistical Model for Image Restoration 

      Wan, Yi; Nowak, Robert David (2001-10-20)
      In this paper we develop a wavelet-based statistical method for solving the image restoration problem. In this approach, a signal prior is set up by modeling the image wavelet coefficients as independent Gaussian mixture ...
