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.

Method and apparatus for simulating radio channel

The invention relates to a method of performing channel simulation and a channel simulator. The channel simulation is performed digitally. At least a section of a signal () to be fed to simulation is transformed by convolution transformation from time space to transformation space in tansformation means () of the channel simulator. In weighting means (), the transformed signal () is weighted by a channel impulse response that is transformed from time space to transformation space. Finally, the resulting signal () is inverse-transformed in inverse-transformation means () to time space.

Method of radio channel simulation and channel simulator

The invention relates to a method and device for performing channel simulation, the device comprising a set of channel simulation units (to) for simulating a radio channel, each unit comprising radio frequency parts (A toA) and baseband parts (B toB). In the solution of the invention, the baseband parts of several different units (to) are arranged to simulate the same channel.
