SIGNAL SEQUENCE ALLOCATING DEVICE AND SIGNAL SEQUENCE ALLOCATING METHOD

To efficiently and appropriately allocate signal sequences, a signal sequence allocation device (1) includes a cell radius calculation module (2) that calculates an area radius of an area in communication areas to which a signal sequence is to be allocated, a signal number calculation module (5) that calculates the number of signals in a signal sequence to be allocated to a communication area based on the area radius, and a signal sequence allocation module (7) that allocates a signal sequence to a communication area based on the number of signals.
