Abstract :
In this paper, we introduce the practical blind interference suppression receiver, for joint acquisition and demodulation of CDMA signals. Regarding to the time delay estimation, a new and practical method of handling the mismatch in multi-path fading channel is proposed. Furthermore, by efficient exploiting the channel diversity and mismatch handling, significant improvement in the BER performance of final receiver, which is the outcome of acquisition mode, is obtained.
