...In [ 31 ], the joint interpolation, decimation and filtering (JIDF) algorithm, which employs one pair of a interpolator and a reduced-rank filter together with a group of decimation units, provides a significant improvement in terms of convergence and SINR performance for code-division multiple-access (CDMA) applications....
