Abstract:
This invention relates to a receiver circuit which comprises an equalizer (27) and an error decorrelator (25). The error decorrelator being configured for changing (501; 601, 602) the position of symbols. The invention further relates to a corresponding method. This invention finally relates to an interleaving or deinterleaving method which comprises selecting a first number of symbols (204; 302) within a stream of digital data (13; 28) thereby obtaining selected symbols. The method further comprises exchanging (601, 602) the position of at least half of said first number of symbols of said selected symbols with the position of other symbols from said selected symbols. The invention further relates to an interleaving or deinterleaving circuit.
