Paper Abstract

This paper provides a system level description of a mixed video/data CDMA transmission model. We propose the combination of rate compatible punctured convolution (RCPC) code for the wireless physical (PHY) layer and CDMA RAKE receiver for wireless mixed video/data traffic which can be sent over indoor wireless channels. Through numerical analysis, using a frequency selective multipath Rayleigh fading channel model, it is shown that RCPC coding at the wireless PHY layer can be effective in providing reliable wireless CDMA network. And the proposed scheme that combine RCPC coder and CDMA RAKE receiver provides a significant gain in the BER and PER performance over multipath fading channels.
