Abstract
A pulse stuffing technique is used to eliminate the silent gaps in
the transmission of a particular Spread Spectrum system. Unauthorized
listeners now have more difficulty in recovering the message content.
A two code device was built using both a pseudorandom maximal
length code and a Golay complementary sequence code. The pseudorandom
code was used for pulse stuffing an umbrella code and was
discarded after a digital matched filter in the receiver. The Golay code
was added with a Surface Acoustic Wave dispersive element and removed
with a similar device used as a matched filter.
