Implementation of an adaptive equalizer for digital radio communications

Using a simplex optimization method, the authors present a new structure for an IF adaptive equalizer using a multi-stage Bode bell network. It is controlled by a microprocessor with an improved Kalman algorithm. An equalizer using the parameters given by computer aided design (CAD) is implemented. The proposed structure has been simulated and tested, and its performance thereby demonstrated. The simulation results show that the proposed structure is capable of providing significant compensation for the spectrum distortion during multipath selective fading
