    Bit Interleaved Space-Time Codes
    (2001-09-20) Muharemovic, Tarik; Gatherer, Alan; Ebel, Will; Srihosour, Srinath; Hocevar , Dale; Huang, Everest; Center for Multimedia Communications (http://cmc.rice.edu/)
    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 codes, naemly bit interleaving. Subsequently we provide a computationally effective, iterative way of decoding bit interleaved space-time codes. At the end we note the 2dB gain due to the new approach. We note the sixteen state code which operates close to 3dB from the outage probability.

    Space-Time Codes with Bit Interleaving
    (2001-11-20) Muharemovic, Tarik; Gatherer, Alan; Ebel, Will; Srihosour, Srinath; Hocevar , Dale; Huang, Everest; Center for Multimedia Communications (http://cmc.rice.edu/)
    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 effective, iterative way of decoding bit interleaved space-time codes. At the end, we note the 2dB gain due to the new approach. A proposed 16 state bit interleaved code operates close to 3dB from the outage probability.
