Research and application of pseudo-random sequence

Random sequence is very important in the practice of modern science,but because of the discommodity in use,the concept of pseudo-random sequence is introduced.M-sequence is the first pseudo-random sequence that is used in practice,it has favorable randomness and balance,but it has great weakness in quantity,then the Gold-sequence which is based on the m-sequence is engendered.In this paper,the common attributes of the pseudo-random sequences and the respective properties of m-sequence and Gold-sequence are thoroughly researched.The concrete application of the pseudo-random sequence in the practice of modern science is discussed.
