Abstract
In a method, an apparatus and a system for data transmission, a plurality of transmitters are provided, which operate according to a communications standard for data transmission with a bandwidth that is higher than the transmission bandwidth. The transmitter is adapted to the transmission bandwidth, and the plurality of the adapted transmitters are allocated to different carrier frequencies in the transmission bandwidth for parallel data transmission.
Claims13
A method for data transmission over a transmission channel providing a channel bandwidth for the data transmission, comprising:
- providing a plurality of transmitters, each of the plurality of transmitters operating according to a communications standard for data transmission, the communications standard defining a data transmission bandwidth, the data transmission bandwidth being higher than the channel bandwidth;
- and
- adapting each of the plurality of transmitters such that the data transmission bandwidth of each transmitter corresponds to the channel bandwidth;
- wherein adapting each of the plurality of transmitters comprises reducing the data transmission bandwidth of each of the plurality of transmitters to a subrange of the channel bandwidth by reducing the clock rate of each of the plurality of transmitters;
- and
- wherein
- at least some of the adapted transmitters are allocated to different carrier frequencies in the channel bandwidth for a parallel data transmission.
