Channel value calculating and equalisation system for use in multiple carrier wave system |
摘要 |
The modifying auxiliary device is used to modify the compensation parameters in small stages so that an equalisation auxiliary device converges in the inverted channel model. An output signal (U) from the auxiliary device is fed to a detector/quantifying auxiliary device, and an output signal (Y) from the detector/quantifying auxiliary device is fed to a first input on the modifying auxiliary device. An output signal (EQ) from the modifying auxiliary device is fed to the compensating auxiliary device. The output signal, Y, is fed to a symbol decoding auxiliary device which produces a decoded data flow. The modifying auxiliary device is operatively connected to a variance value calculating auxiliary device, which is arranged to produce a signal (W) which indicates an interference variance on each of the carrier waves in the multiple carrier wave system. |
