1. A base station in a wireless communication system, the base station comprising:
a master Field Programmable Gate Array (FPGA);
a plurality of slave FPGAs controlled by the master FPGA; and
an address masker coupled to the master FPGA and the plurality of slave FPGAs,
wherein the address masker is configured to:
receive different address bits assigned respectively to the plurality of slave FPGAs by the master FPGA;
identify a masking range by identifying the different address bits corresponding to the plurality of slave FPGAs;
for the different address bits, mask bit values at a specific position with same value within the masking range; and
transmit masked address bits corresponding respectively to the plurality of slave FPGAs.
