The hybrid implementation of the multistage constant modulus CM array is designed for separating correlated signals. The canceller weights in the cascade structure provide estimates of the direction vectors of the captured signals. These estimates are then used in a parallel implementation of the linearly constraint CM (LCCM) array leading to the hybrid structure. In this paper, the hybrid implementation is extended to a three stage case for separating three correlated signals. The three correlated signals are of equal power and randomly generated. Mean Square Error (MSE) learning curves indicate that the proposed hybrid LCCM algorithm converges faster and has lower MSE than the conventional cascade implementation.
