A modified constant modulus (CM) algorithm based blind multiuser equaliser with a decision directed (DD) scheme is developed that does not require any mutual decorrelation and is suitable for downlink direct sequence code division multiple access systems. The performance of the proposed time domain adaptive equaliser is evaluated with respect to usual parameters and is found to perform better than...
A novel block-based normalised least mean square (NLMS) algorithm with set-membership filtering criteria is proposed for symbol rate decision feedback equalisation. The introduced algorithm provides substantial reduction in filter weight updating operations and low bit error rate (BER) while keeping the convergence speed almost the same as existing algorithms for the same purpose. It is shown in the...
