Abstract: A method for designing a digital system with a high-level programming language is provided to reduce time required for simulating a program made in a low-level programming language and reduce the time required for forming a system hardware configuration with a lower program by forming the system hardware environment with the high-level programming language. An algorithm and the first variable for the desired digital system are set by using the high-level programming language. The environment similar to the desired system hardware is formed based on the set algorithm and first variable by using the high-level programming language(S110). The system environment formed in the high-level programming language is converted into the low-level programming language and is implemented to the hardware(S140).

Abstract: An AGC(Automatic Gain Control) method having variable gain control intervals and a device thereof are provided to perform a rough gain control loop in a wireless communication system having multiple antennas, and additionally conduct a detailed gain control loop for receiving signals passing through a gain control process, thereby obtaining stable gains. RF(Radio Frequency) receivers(110) receive a plurality of the first signals through plural antennas, and perform gain control for the received first signals to output the first signals as a plurality of the second signals. A signal saturation sensor(400) outputs a saturated state determination value if the number of the second signals larger than a threshold value is more than a predetermined number. A gain controller(300) detects one power by comparing power of the second signals, and outputs the detected power and a gain determination value determined on the basis of the saturated state determination value to the RF receivers(110).
