In terms of Bit error rate (BER) and synchronization performances, Markovian codes are superior to i.i.d. codes in asynchronous mode, for singleuser case. Their BER performance is better than i.i.d. codes in case of multiuser detection (MUD) also. This paper shows that a simple code acquisition scheme based on statistical properties of spread spectrum (SS) codes efficiently makes performance of Markov codes to be superior to i.i.d. codes in asynchronous MUD systems. Hence, Markov codes are a strong candidate for being SS codes in MUD case as well. Furthermore, the proposed code acquisition scheme significantly outperforms conventional schemes.
