Abstract
Disclosed is a transmission device capable of reducing quantization errors in nonlinear quantization of IQ signals. In the device, a standard deviation measuring unit measures a standard deviation σ of the amplitude distribution of input signals. A kurtosis measuring unit measures the kurtosis of the amplitude distribution of the input signals. A correction coefficient determining unit determines a correction coefficient α corresponding to the kurtosis of the amplitude distribution of the input signals. A quantization unit quantizes the input signals using the correction coefficient α and calculates quantization data. A multiplexing unit multiplexes the quantization data and quantization control information with each other.
