Channel Estimation Techniques in the Forward Link of CDMA2000 1xEV-DO
Qi Jiang · Journal of Huaihai Institute of Technology · 2005
IxEv-DO is the data-enhanced system of CDMA2000. Using multilevel modulation technology, the system needs an accurate channel estimation algorithm, and conventional channel estimation algorithms can not achieve the recommended minimum performance standards. In this paper, we introduced the WMSA into EV-DO, and put forward the estimation algorithm of using MAC channel into assistant pilot channels. Simulation results proved that our estimation algorithm could remarkably improve the accuracy of channel estimation and the system performance.
