Abstract
In this paper, two iterative algorithms for NDA (nondata_aided) channel estimation are introduced to the DSJJWB system. The two iterative algorithms are named MMSE (minimum-mean-square-error) iterative algorithm and NMMSE(nonminimum-mean-square-error) iterative algorithm. The BER performances of the MRC Rake receiver with the two iterative algorithms are verified and compared via simulations. The simulation results show that the MMSE iterative algorithm performs better than NMMSE iterative algorithm for NDA channel estimation.
