Abstract
A method and arrangement for simulating a radio channel. In the solution, a channel having paths is simulated and the delay of each path is formed separately with a low-resolution delay arrangement and a high-resolution delay arrangement in such a manner that the simulated delay of each path is the sum of the low-resolution delay and the high-resolution delay. Low-resolution delaying is performed on each path discontinuously as multiples of a predefined minimum delay. For each signal delayed by a low-resolution delay, at least one fixed, high-resolution delay is selected, which is a predefined part of the predefined minimum delay of a the low-resolution delay. Each signal delayed by a low-resolution delay is delayed by at least one selected high-resolution delay to form a path-specific total delay.
