In this work a multiplicative neural network (MNN) based adaptive equalizer is proposed. Multiplication increases the computational power and storage capacity of neural networks is well known from extensions of artificial neural networks where this operation occurs as higher order units. Multiplicative node functions allow direct computing of polynomials inputs and approximate higher order functions with fewer nodes. The MNN based equalizer is tested on 4 QAM, 16 QAM and 32 QAM signals for AWGN channel noise model. The equalizer is implemented for six different FIR channels using 4 QAM signals...
