A New Method of Generating Discrete Walsh Function and Simulation
Hua Zhao · Journal of Jinling Institute of Technology · 2005
This paper introduces a new generator of discrete Walsh function, with which we get three common Walsh codes with different orders, and then discusses their relationship. Then the circuit frame of the new Walsh functional sequence generator is designed and given. Finally, simulation of software is made by using Matlab language. The results show that the new method can simplify design and reduce cost. Discrete Walsh function can be used in the CDMA communication system to evidently decrease bandwidth, and improve using efficiency of channel band. In conclusion, the new generator of Walsh code has good practicality.
