Performance Comparison of Hmm Discrete Channel Modeling in Cdma Links
Debjani Mitra, Rakesh Ranjan · International Journal of Computer Applications · 2010
The performance comparison of two Markov models namely the Baum Welch Algorithm based HMM and Semi Hidden Markov Model has been evaluated for a DS-CDMA link in this work.The simulation includes the effects of AWGN, Multipath and Multiple Access Interference.Validation includes a comparison of the runlength statistic for the original and regenerated error sequence from estimated models.The SHMM approach is seen to be capable of developing a more accurate model as compared to the BWA.The length of number of symbols processed at a time does not affect the accuracy in both the methods.
