Specialty of art design has highly integrated disciplines and more strongly practicing of professional technical skills. Along with the social demands for higher professional is greater today, the educators of University shoulder a mission of the education and training of creative students for art design. In view of the current situation and the analysis of existing problems, the changing of the concept of training education and the ways of cultivating creative students of art design are reached in the paper and presented some valuable viewpoint for discussion.

We consider the impact of multiple access interference (MAI) on noncoherent code tracking loops (in conventional CDMA matched filter detectors) and a novel interference canceller is proposed in order to eliminate the steady-state tracking error, reduce the RMS tracking jitter and realize fast and reliable synchronization. We introduce the idea of multiuser detection such as successive interference cancellation. Simulation results demonstrate the loop exhibits a higher performance than that of the conventional code tracking loop.

Code division multiple access (CDMA) has attracted considerable attention in digital cellular mobile and personal communications. We propose a novel multiuser detector based on the reduced state Viterbi algorithm. It partitions the total K users into G groups according to their power strengths and interference levels, which reduces the computational complexity per binary decision from O(2/sup K-1/) to O(G*2/sup K/G-1/) for asynchronous DS/CDMA systems in AWGN. Theoretical analyses and simulation results are presented to demonstrate the significant performance improvement over the successive interference canceler (SIC).
