Abstract
A method, apparatus and computer program is described comprising: obtaining aggregated reference signals received from multiple signal carriers over channels of a mobile communication system, said signal carriers having different carrier frequencies; initialising: a first matrix, a channel power matrix and a noise estimate; and sequentially updating: a channel impulse response estimate, said channel power matrix and said noise estimate using mathematical maximisation; a second matrix; a vector of channel frequency offset; and the first matrix. The sequential updating is repeated until a termination condition reached.
