Tittle:
Radio transmission technique with two free space modes
Summary:
A German University developed a radio transmission technique that exploits two free space modes of the same frequency for transmission. The main advantages are a simple design that reduces the number of devices and a reduction of power consumption. The German University offers licenses to companies active in the communication sector or the possibility of a technical cooperation in order to advance the technology.
Description:
Most current radio transmission techniques use locally generated signals for the
demodulation of the received signals. The electronic devices like synthesizers and local oscillators needed for the demodulation are expensive and require much space.

A German university offers a technique that exploits two free space modes of the same frequency for transmission. In addition to the wanted signal the emitter provides a signal at the same frequency for the demodulation, which is orthogonal to the wanted signal. Thus there is no need for a local oscillator or a synthesizer in the receiver, which means significant reduction in the number of electronic devices. Besides this the requirements on the transmitter oscillator are much less than in conventional system as wanted signal and demodulation signal originate from the same source. Additionally there is also a significant decrease of power
consumption. Especially in the GHz-range this technique has obvious cost advantages.
It can be used with almost all modulation schemes and it is insensitive to the Doppler effect as the signal for demodulation is sent with the wanted signal.
An interesting field of application is short range transmission like car to car communication, RFID-technology or chip to chip communication to replace connections by wire.

Industrial partners from the communication sector are sought for licensing or technical co-operation to adapt the technology to their applications and to advance it.
Advantages and Innovations:
- Simple design: Compared to conventional systems there is a reduced number of devices
- Power consumption is reduced
- Low requirements to sender oscillator
- Applicable to the most modulation schemes
- Simple application
- Up to the high GHz-range
- Insensible to Doppler-effect
