Abstract
Message symbols are sent radio transmission using an ultra wideband transmitter emitting a pulse-phase-modulated transmission signal that has isolated pulses, each of which has a time offset in relation to a time pattern, which time offset is dependent on a message symbol that the pulse represents. The transmission signal has a line spectrum having a multiplicity of modulated frequency lines. The transmission signal is received at a receiver, which obtains a narrowband signal from a single one of the modulated frequency lines. The modulated frequency line includes a bandwidth that corresponds to less than twice a pattern frequency of the time pattern. A phase of the narrowband signal is ascertained at predetermined instants and the respectively ascertained phase is associated with one of a plurality of predetermined message symbols.
