摘要:
The invention describes a transmission system with transmitter, transmission line and receiver, where the transmitted signal is modulated by a diffential phase shift keying modulation scheme. This is realized in a differential coder and a phase modulator. The diffential coder comprises an EXOR circuit, with a time delay of at least 2 bit in the attached feed back loop.
