PURPOSE: Apparatus for maintaining the receiving signal's level of CDMA base station is provided to enhance a board space' utility, and prevents a power-consumption by making a prior RPROM's construction with FPGA or EPLD. CONSTITUTION: A first coder(100) is changed according to a time by a pre-stored numerical equation, an input value is inserted to the equation, and a calculation result value is outputted. The second coder(200) performs the same function as the first coder. A full adder(300) adds a transmitted result value from the first and second coders, and transmits the added result value. A saturation part(400) receives an output value of the full adder, transmits the output value if the output value is over a predetermined value. Or, the saturation part(400) saturates the output value of the full adder(300) if the output value is below a predetermined value. Thereby, a receiving signal's level of CDMA base station can be maintained thereby enhancing a space utility. |
