Mobile communication system using adaptive transmission
A method for decoding a wireless transmission in a communication system, particularly for mobile communications, comprising a plurality of receiver stations communicatively coupled to a common decoder station, wherein the receiver stations transmit digital representations of received user signals to the common decoding entity. These digital representations are initially transmitted to the common decoder station in coarse granularity, and in case the decoder station cannot decode the transmitted digital representations of one or multiple user signals, the decoder requests a refined digital representation of the received signals from at least one receiver station.
1. Method for decoding a wireless transmitted signal at a common decoder station comprising the steps of
receiving the signal at a receiver station, said receiver station being communicatively coupled to the common decoder station,
digitizing the signal in the receiver station thus producing a digital representation of the signal,
transmitting a first digital representation of the signal at a first fineness to the common decoder station,
requesting additional information about the signal from the receiver station in case decoding of the digital representation of the signal cannot be performed successfully, the additional information enabling the common decoder station to process a refined digital representation of the signal, and
determining the probability of successfully decoding the refined digital representation.
2. The method of claim 1 , further comprising the step of Fourier transforming the digital representation of the signal before transmitting the digital representation of the signal to the common decoder station.
3. The method of claim 1 , wherein the method steps of receiving, digitizing and transmitting the signal to the common decoder station are performed in a plurality of receiver stations simultaneously.
4. The method of claim 1 , wherein the first digital representation of the signal comprises the most significant bits of the digital representation of the signal only.
5. The method of claim 1 , further comprising the step of signalling a successful decoding from the common decoder station to a receiver station.
6. The method of claim 1 , further comprising the step of storing a digital representation of the received signal in the receiver station.
7. The method of claim 1 , further comprising the step of instructing a receiver station to increase the fineness of a transmitted digital representation by providing additional information on previously received signals, or to increase or decrease the fineness of the transmitted digital representation of signals to be received in the future.
8. A cellular communication system for decoding a wireless transmitted user signal comprising at least one receiver station and a decoder station, the receiver station communicatively coupled to the decoder station, and wherein
