A wireless mobile device comprising a tuner for converting a received radio frequency signal to a base band signal or intermediate frequency signal and providing the base band signal or intermediate frequency signal to a receiver, wherein the receiver is arranged to provide received data associated with the base band signal or intermediate frequency signal to an application processor for storage in memory, wherein the application processor is arranged to extract the data from memory in an interleaved form and perform error correction on the interleaved data.

Wireless mobile device

An arrangement () and method, for iterative channel impulse response estimation in a system such as a GSM/EDGE system employing a transmission channel, by: producing () from a received signal (y) a channel impulse response estimate signal (p); and producing () from the received signal (y) a noise estimate signal (w) which is iteratively fed back to improve the channel impulse response estimate signal (p). The noise estimate signal comprises a matrix (w) respresenting the inverse of noise covariance; the matrix may be calculated at each iteration or may be selected from predetermined values corresponding to statistics of expected noise. This provides the advantages of reduced complexity, independence of the equalization method used to produce the channel impulse response estimate signal, and consequent performance improvement.
