Application of Variable Step Size LMS Algorithm in Multiple Access Interference Cancellation
Hui Zhi Zou · Applied Mechanics and Materials · 2014
MAI influence, using a low computational complexity variable step size LMS algorithm based on the traditional algorithm to find the optimal weight on, and make estimates for the magnitude, thereby offsetting the presence of MAI and estimates for spread spectrum communication system struck a balance between the consideration to be paid for MAI. The improved algorithm reduces the computational complexity of each level, the simulation results also show that the method has better performance.
