INTERFERENCE SUPPRESSION IN DSSS SYSTEM BY QUADRATURE DEMODULATION NEURAL NETWORK

Zoran Dobrosavljević and Miroslav Dukić

Abstract: In this paper a DSSS receiver with the quadrature demodulation and neural network is presented. Extended Kalman algorithm is used for the network coefficients adaptation. Results, given as BER, show that the neural network receiver performs better in the presence of the strong broadband interference.

Key words: Neural network, quadrature demodulation, Kalman algorithm, spread spectrum, inteference.
