Abstract:
1. A method for automatically adjusting parameters of signal emitter of a synchronous high-speed transmission system wherein controller of signal receiver could transmit information to the controller of said signal emitter, said method comprising: selecting a first subset of values in a predetermined set of values: sending a request to said controller of said signal emitting means for setting said parameters to the values of said selected subset; evaluating the quality of the signal received by said signal receiver; if all subsets of said predetermined set of values have been selected, determining the subset corresponding to the best signal quality and sending a request to said controller of said signal emitter setting said parameters to the values of said determined subset, setting said phase rotator in a first position; initializing a partial value associated to said phase rotator position; sampling the received signal; XORing said sample and said sample shifted by 1 bit; ORing the result of said XOR operation with said partial result associated to said phase rotator position; replacing the value of said partial result associated to said phase rotator position by the result of said OR operation; repeating the last four steps during a predetermined time; setting said phase rotator in a second position and repeating the last six steps; and, combining said partial results associated to said first and second positions.
