Abstract :
A new method is presented for complex FIR filter design. This method formulates the FIR filter design as a semi-infinite quadratic optimisation (SIQO) problem, in which the mean squared error between the desired response and the designed filter is minimised and a set of linear inequality constraints is used to ensure that the peak gain in the stopband satisfies the prescribed specifications. Simulation is used to illustrate the effectiveness of the proposed method
