Abstract
A method for determining an inverse impulse response of a communication channel by means of a PAM receiver comprises the following method steps: switching on the PAM receiver; if a second PAM transceiver is switched on, setting a difference between a clock frequency of the data signal and a sampling frequency of the first PAM transceiver; comparing a symbol that is output by the interpreter with a state that is supplied to the interpreter, and outputting an error value, wherein in each case a symbol associated with a sampling clock is compared with a state associated with the same sampling clock; adapting m filter coefficients of the equalizer to minimize error values; repeating the third method step and the fourth method step until an error limit value is reached.
