LMS algorithm fixed-point modeling designated based on System Generator modules

LMS Algorithm floating point arithmetic in hardware implementation system takes up more resources, hardware running slow and can not meet the real-time requirements of the system. So we need fixed-point arithmetic for LMS algorithm. Doing algorithm modeling with System Generator in Simulink environment will be implement in ISE and MATLAB. We can make adjustments and do the corresponding design and simulation for fixed-point methods . Simulation results show that fixed-point arithmetic module can cellation noise well. But compared with floating-point arithmetic modules, there are a little errors. LMS algorithm module can achieve LMS algorithm effectively. In the Simulink environment ,it lay a good foundation for complex system fixed-point implementation.
