This paper proposes a narrowband interference (nbi) suppression algorithm for direct sequence-code division multiple access systems. The nbi is considered from heterogeneous networks, and predicted based on its cyclostationary characteristic using a nonlinear feed-forward neural network predictor which eliminates the nonlinearity of the spread spectrum (ss) signal in the nbi prediction.

We investigate the estimation of the directions-of-arrival (doa) of closely spaced narrowband cyclostationary signals in the presence of multipath propagation.
