Empfänger und Verfahren mit einer vorwärtsgekoppelten datengestützten Kanalschätzung

摘要

To perform interference suppression for a received signal more precisely. Block dividing section divides a data part of a received slot into several blocks. Channel estimator calculates a channel estimate vector for each block and stores it into channel estimate storage device. Channel estimate calculator for each block calculates a channel estimate vector for each block by using a channel estimate vector calculated with a known series symbol part for the (current) slot and a channel estimate vector for a known series symbol part for a previous slot stored in channel estimate storage device. Then, channel equalizer and de-spreader perform a calculation such as a channel equalizing calculation by using a channel estimate vector for each block at each block.
