Data communications system uses transmission signal to send defined bit or bit sequence. with amplitude or phase different from amplitude or phase of signal associated with bit or sequence

摘要

The system has a transmission unit that sends modulated transmission signals to a receiver unit over a transmission channel, whereby each bit or bit sequence to be transmitted is associated with a defined amplitude and phase. A transmission signal (6a) is used to send a defined bit or bit sequence (a) with an amplitude or phase that is different from the amplitude or phase of the actual transmission signal associated with the bit or bit sequence. AN Independent claim is also included for the following: a transmitter unit and a data transmission method.
