* \brief This block evaluates the peaks given from a OFDM matrix. Input are the bins of the peaks with the identifiers 'axis_x' and 'axis_y'. The parameters of the block axis_x and axis_y are vectors which define the mapping of the axis. If two values are given it is assumed a linear progression in between. If four values are given the middle values are set on half of the axis and it is interpolated linear in between. len_x and len_y gives the length of the axis in number of bins. symbol_x and symbol_y defines the identifier (symbols) for the output data. merge_consecutive toggles merging consecutive peaks. Each peak is compared with peaks in a range of one bin. If there is a peak with a higher power the actual bin is not used for evaluations. If merge_consecutive is true data with identifier 'power' is needed.
