Correlation-constrained CMA adaptive array using cyclostationary signal properties

We have proposed the constant modulus algorithm (CMA) adaptive array under the cyclic correlation constraint suitable for mobile communications. Via computer simulation, we have shown that the correlation constrained CMA (CC-CMA) gives a better signal capture performance even at the low input signal to interference ratio. In particular, it is verified that the CC-CMA in which the control vector is optimized by the CR-SCORE algorithm (Agee et al. 1990) provides the best performance in our simulation.
