¿µ¹®³»¿ë¿ä¾à | This standard graphically describes the relation between necessary bandwidth (or occupied bandwidth) and unwanted emission domain and presents a simple calculation of occupied bandwidth by using K values obtained from a cosine roll-off shape filter. Also, the standard includes an analytical calculation expression for the occupied bandwidth of a multi-carrier system. | ||
