Abstract: A method (10) of regenerating a signal is provided. The method involves sampling (13) a received signal to obtain a plurality of samples each having an associated magnitude. The samples are sorted (15) to obtain a statistical distribution (which may be a histogram). Known distributions are fitted to the statistical distribution using a fitting operation (16, 17), and for each a measure of similarity is obtained. A matched distribution is then determined from the measures of similarity (18), that is subsequently used to regenerate a signal (12) that itself is statistically representative of the originally sampled signal. Such a method mitigates the storage burden associated with the recording and subsequent regeneration of representative wireless signal environments for wireless device testing. Also relates to an apparatus for the same.
