Abstract :
In Max quantiser design, a numerical method is usually employed to solve the Lloyd-Max equations. Poor accuracy and slow convergence rate are observed in most of the algorithms used. A fast convergence method is proposed here to generate the Max quantiser with minimum mean-square error. This is achieved by changing the integration limits and using a bisection method in solving the Lloyd-Max equations.
