摘要

A method for determining the search order of nodes in the case of a tree such - algorithm for the detection of more point - to - more point - received signals having a quadrature amplitude modulation (qam) which, by means of a qam - constellation is determinate, in a telecommunication system, characterized in that rearranges the searching order for a receiver symbol by means of a geometrical analysis of a relative position (pos) in respect of the received symbol constellation points of a potential transmitter symbols existing grid in an iq - plane of the qam - constellation is approximated, wherein a first element of the search order by rounding of the position of the reception of symbol y_i'''' to the next constellation point (1) of the grating is determined from potential transmitter symbols.
