1. A method for simulating a radio channel, comprising:
- simulating the radio channel utilizing user data describing radio signal and radio channel data describing the radio channel at different instants of time, and the simulation filtering the user data using one or more FIR blocks in a FIR filter based on the radio channel data;
analysing the radio channel data before simulation and/or during simulation for localizing significant user data values in respect of the radio channel at different instants of time; and
transferring at least one of the FIR blocks at a delay level depicting a radio channel delay during simulation in such a manner that the FIR blocks cover the localized significant user data values.

Abstract
A radio channel simulator configured to read radio channel data describing a radio channel and user data including at least one user signal, and to simulate the radio channel using a FIR filter comprising one or more FIR blocks for filtering the user data read based on radio channel data in connection with the simulation. The radio channel simulator is configured to transfer at least one FIR block at a delay level depicting a radio channel delay during simulation.
