Abstract: PURPOSE: An active RFID device with improved PN code generation is provided to satisfy magnetic autocorrelation property and cross-correlation property when performing an additional transmitter, thereby easily distinguishing different codes. CONSTITUTION: The first XOR operator(431) inputs output bits from two flip-flops of bit shifter(420). The first XOR operator outputs the output bits through the inputted output bits. The second XOR operator(432) inputs output bits from two different flip-flops of the bit shifter. The second XOR operator performs XOR operate and outputs the output bits through the inputted output bits.

Abstract: PURPOSE: A pseudo noise code generation device and a method for the same are provided to perform an XOR operation on specific output values by stages, thereby generating a pseudo noise code with shift and add properties. CONSTITUTION: A PN(Pseudo Noise) code generation device(200) includes a memory device unit(210), an XOR operation unit(220) and a PN code generation unit(230). The memory device unit includes multiple memory devices. The XOR operation unit receives output values of at least two memory devices among output values of the multiple memory devices. The XOR operation unit outputs an XOR operation value of the output values of the memory device. The PN code generation unit generates a PN code based on the output value of the XOR operation unit.
