See below: ```c transportSignalCrossCorrelation_64[bin] = W_add( transportSignalCrossCorrelation_64[bin], W_mult0_32_32( L_shr_sat( inRe_fx[0][slot][bin], sub( q_cldfb[0][slot], common_q ) ), L_shr_sat( inRe_fx[1][slot][bin], sub( q_cldfb[0][slot], common_q ) ) ) ); // Q(2 * common_q) transportSignalCrossCorrelation_64[bin] = W_add( transportSignalCrossCorrelation_64[bin], W_mult0_32_32( L_shr_sat( inIm_fx[0][slot][bin], sub( q_cldfb[0][slot], common_q ) ), L_shr_sat( inIm_fx[1][slot][bin], sub( q_cldfb[0][slot], common_q ) ) ) ); // Q(2 * common_q) ``` Effect depends if the Q-value is differing. <!--- Below are labels that will be added but are not shown in description.
