PROBLEM TO BE SOLVED: To reduce the number of required quantization bits although in the prior art, the number of quantization bits increased because a quantization step is set in conformity with a radio signal with a small amplitude value and a dynamic range is set in conformity with a radio signal with a large amplitude value.SOLUTION: A distributed radio communication base station system of the invention divides a radio signal into multiple radio signals, matches required quantization steps and dynamic ranges by adjusting the amplitude of the divided radio signals such that all of it will be the same, or determines a required quantization step and a dynamic range per divided radio signal, and thereby reduces the number of required quantization bits. |
