Apparatus and method for the iterative fault compensation for the mobile reception of ofdm - signals in rapidly variable multipath propagation channels -

摘要

Receiver for the intermetallic - carriers - interference - compensation (ici - compensation) in an orthogonal frequency division multiplexing system (ofdm - system), wherein the receiver comprises:an ofdm - demodulator (302) for demodulating a received ofdm - signal r [1] to an input signal y [l];a first estimating means (304) for estimating and equalizing of the estimated transmission values x ^⁽⁰⁾[l] and a channel matrix h ^⁽⁰⁾[l] from the input signal y [l];a ici - reducing agent (308) for reducing the ici of the input signal y [l] using the estimated transmission values x ^⁽⁰⁾[l] and the channel matrix h ^⁽⁰⁾[l];a reversal of imaging - and error correction means (306) for forming the inverse mapping and for correcting errors of the signals y ~ [l] with a reduced ici and to form of an output signal x ^ [l];characterized in thatthe receiver (300) further comprises a new encoding means (307) for the iterative recoding and mapping of the output signal x ^ [1] as a new estimated transmission values x ^^(j)[l]; whereinthe ici - reducing agent (308) for reducing an ici of the input signal y [l] using the new estimated transmission values x ^^(j)[l] is designed.
