Basic theoretical considerations of communications with electromagnetic Walsh waves are presented. The spectra of unmodulated Walsh waves radiated from a small electric dipole are computed for ideal and trap ezoidal approximations to Walsh function excitation. A link analysis based upon matched filter detection of the radiated Walsh waves received in thermal noise is presented. It is shown that the current required on the radiating element is proportional to the square root of the bit rate-to-carrier sequency ratio.
