From ten of its functions strongman widely (IJ ten should be a lot of engineering fields. In spread spectrum communications,), the usual practice is spreading sequences (IJ and J signal x, resulting in the expansion of the spectrum or twisting shrinkage, thus the performance of direct sequence spread spectrum determines the quality of communication. Pseudo-random sequence,), the m sequence and Cold sequence () J are the most common one spreading sequences. The article first introduces Jane m sequences and sequences Cold Principle, performance and construction methods. Then MAfLAB)))) IJ M programming language to achieve their production and analysis. The simulation results confirm the correctness of the method and feasibility. The method is concise and intuitive for engineering and technical staff.
