of the mixer 126 where it is added to a delayed version of the multicarrier signal at the first input of the mixer 126 on line 120 the delay block 104 merely compensates for the processing delays in the impulse generator and the complex filters which together may be considered an error block 101 the added error signal on line 123 must fulfill the above described frequency constraints and the peak and rvs evm constraints as discussed hereinabove the u201c hard clipper u201d provides an idealized result thus the signal on line 123 should approximate as closely as possible while fulfilling the additional constraints referring to fig3 there is illustrated an example implementation of the error impulse generator block 102 of fig1 the signal on line 300 provides an input to a block 302 which generates a single residual signal on line 304 the residual signal on line 304 is the difference between the original transmitted signal on line 300 and a u201c hard clipped signal u201d thus it represents the error associated with hard clipping the hard clipped signal itself may be generated by limiting the maximum amplitude of the signal to be transmitted on line 300 to a predefined limit the.
