摘      要：A new family of GMW sequences over an arbitrary Galois ring was defined by using the trace functions and *** generalizes the concept of GMW sequences over finite *** the Fourier representation,we derived an estimate of the linear complexities of this family of GMW *** the result shows that such sequences have large linear complexities.
