A method of enhancing security for the transmission of information

摘要

The method enhances security for transmission of information by utilizing systems of Quasi-Walsh functions to provide a high resilience against jamming and interception and in addition allows multiple access and acquisition.It switches among generalized systems of Quasi-Walsh functions at some rate r, where r may be either a fixed or a variable value not equal to zero. An independent claim describes a method of transmitting bits for an ith user.
