Abstract

In this contribution we investigate an iterative parallel interference cancellation (PIC) aided CDMA MPEG-4 videotelephony scheme. The number of iterations used by the PIC-based turbo receiver was four. The family of m-sequence based spreading codes having a length of N = 15 chips was employed in our system and the transmission burst length was T = 120 bits. A random channel interleaver having a memory of eight transmission bursts was employed. The system considered supported K = 7 users and communicated over an asynchronous symbol-spaced, equal-weight two-path uncorrelated Rayleigh fading channel.
