A novel adaptation strategy is proposed for Acoustic Echo Cancellation (AEC). The new algorithm firstly partitions the adaptive filter into several blocks and the successive blocks with the maximum h norm are considered to be the active blocks. Then the coefficients of the active blocks are adapted with large update probability to ensure the identification accuracy while the zero coefficients are...
Aiming at the defects of BP neural network, analyzed the disadvantages of the genetic algorithm and the common quantum genetic algorithm. Used the diversity of population and the rapidity of convergence of the real-number coded double-chain quantum genetic algorithm which was combined with BP neural network to modify the weights and thresholds of the neural network, and the modified neural network...
