1. A method of detecting a symbol sequence in asynchronous reception, using a known digital sequence, comprising the steps of:

  • a) dividing the known digital sequence into at least two separate segments;

    b) allocating a number of specific threshold values equal to the number of said segments;

    c) correlating said received symbol sequence and the first segment of the known digital sequence, therewith to obtain a first correlation value;

    d) storing said first correlation value at least when said value exceeds a first of said threshold value;

    e) setting a certain first time point in accordance with the length of the second segment;

    f) correlating said received symbol sequence and the second segment of the known digital sequence at said first time point, therewith to obtain a second correlation value;

    g) adding said second correlation value to the stored first correlation value so as to obtain a first summation value; and

    h) comparing said first summnation value with a second of said threshold values, wherewith an indication that said symbol sequence has been detected is obtained when said sum exceeds said second threshold value.
