128 dn = buffer of correlation values (Word16)
129 sign = buffer containing sign of dn elements (Word16)
137 dn buffer is modified to contain the absolute value of its input
139 values in dn buffer
153 This function builds sign vector according to dn buffer It also finds
170 void set_sign(Word16 dn[], i/o : correlation between target and h[]
171 Word16 sign[], o : sign of dn[]
180 // set sign according to dn[]
183 val = dn[i];

245 void set_sign(Word16 dn[], /* i/o : correlation between target and h[] */
246 Word16 sign[], /* o : sign of dn[] */
255 /* set sign according to dn[] */
258 val = dn[i];
268 dn[i] = val; /* modify dn[] according to the fixed sign */
309 dn = buffer of correlation values (Word16)
320 dn buffer contains the sign-adjusted correlation values
339 This function builds the sign vector according to dn and cn, and modifies
340 dn to include the sign information (dn[i]=sign[i]*dn[i]). It also finds
358 Word16 dn[], //i/o : correlation between target and h[]
377 // calculate energy for normalization of cn[] and dn[]
390 s = L_mac (s, dn[i], dn[i]);
397 val = dn[i];

487 Word16 dn[], /* i/o : correlation between target and h[] */
514 /* calculate energy for normalization of cn[] and dn[] */
519 p_dn = dn; /* crosscorrelation values do not have strong peaks, so
543 val = dn[i];
557 /* modify dn[] according to the fixed sign */
558 dn[i] = negate(val);
