Application of DMMSE criterion to DS-CDMA systems
Lin Wang · Journal of Changchun Post and Telecommunication Institute · 2002
Algorithms based on DMMSE(Difference minimum mean square error) criterion of adaptive multi users detector for short spreading sequences DS CDMA systems is proposed. The DMMSE criterion avoids tracking the channel fading, exploits the negligible variation of the fading gain over two consecutive symbols to adjust the receiver, so it is robust to fast fading. The simulation validates the aforementioned theoretical results and indicates that these algorithms are reasonable and practical.
