Abstract :
This article proposes a complete adaptive GDB algorithm, based on conjugate gradient algorithm, which has been widely used in many real-time systems. Compared to GDB algorithm, it can provide faster convergence, which can be used in real-time systems. Further more, it doesn´t need to modify any parameter, when input signal to interference plus noise ratio (SINR) has changed.
