Abstract
A method of estimating a channel for mobile systems with insufficient cyclic prefix length, wherein the channel comprises a plurality of multipath components (,), includes: receiving a signal (y) comprising a plurality of contributions of a transmit signal (x[k], x[k]) transmitted during a plurality of transmission time intervals (n, n−1) on a plurality of sub-carriers of known pilots (k∈P) and a plurality of sub-carriers of unknown data (k∉P); determining an estimate of the plurality of multipath components (,) based on a probabilistic relation between the plurality of first contributions (x[k], x[k]) of the transmit signal, wherein the plurality of first contributions are transmitted during adjacent transmission time intervals (n, n−1), and an observation of the received signal (y[k]) at a subcarrier (k∈P) of the known pilots, wherein the probabilistic relation is based on statistical properties of the plurality of first contributions (x[k], x[k]) of the transmit signal.
