Apparatus and method for GMSK baseband modulation based on a reference phase to be simplified

摘要

The present invention is an apparatus and method for performing a Gaussian Minimum Shift Keying baseband modulation based on a reference phase to be simplified. The invention mainly comprises: a memory unit storing a plurality of parameters and their corresponding tabular data of a low pass Gaussian filter, the parameters and their corresponding tabular data being simplified in advance; the low pass filter being used for reducing the bandwidth of the apparatus and increasing the utilization of the bandwidth; and a processing unit based on the input digital data and the tabular data in the memory unit to generate the digital in-phase signal I_n and the digital quadrature-phase signal Q_n.
