ABSTRACT:
One aspect of the present invention is a method for combining a direct sequence spread spectrum signal comprising signal components that each may be characterized by a space variable and a time variable comprising the steps of: dispreading the signal components; and determining a set of combining coefficients from the signal components using a Minimum Mean Square Error combining method that considers the space and time variables of the signal components in parallel. The Minimum Mean Square Error combining methods may utilize iterative methods such as the Least Mean Squares method or the Recursive Least Squares method.
