High-frequency radio transmitter for pseudo-randomly phase-modulated signals

摘要

According to the invention, the phase of the high-frequency carrier is directly keyed up pseudo-randomly during the signal processing in a telecommunications system operating with pseudo-random phase shift keying so that the hitherto conventional up-converter is thereby no longer required. A transmitter designed according to the invention is used in interference-immune spread spectrum telecommunications systems which operate with pseudo-random phase shift keying. <IMAGE>
