NOISE GENERATOR FOR FEMTO CELL

摘要

A noise generator for the femto cell capable of applying the generator to mobile communication such as 2G, 3G wibro or LTE is provided to supply a desired service by acquiring a cell on a femto AP side by a user terminal. A VCO1(Voltage Controlled Oscillator 1)(702a) outputs the first oscillation signal of the fixed frequency. A VCO2(702b) inputs the first oscillation signal as the voltage for controlling the oscillation frequency. The second voltage controlled oscillator outputs the second oscillation signal in which the frequency is controlled as the noise floor. The macro cell is formed by the base station.
