“…For different filter lengths (20,50,80,120,200,400), the coefficient word lengths were varied (12, 16, 20, 24 bits) to compare the LO and LD requirements. For filter lengths of 20,50,80,120,200, and 400, the average reductions in LO achieved by [1] as compared with [9] is 9.7%, while reductions of 12%, 13%, 18.5%, 5.6%, and 30% were achieved for CRA-2 [15], NR-SCSE [6], CSDC [21], MAG [19], and C1 [22], respectively. These comparison results are directly taken from [1].…”
