Abstract: First and second input signals to be transmitted are separately modulated based on symbol mapping. A phase value is selectively adjusted for the modulated first and second input signals. The selectively phase-adjusted first and second input signals are separately angle modulated. The angle-modulated first and second input signals are transmitted.

Abstract: Provided is a data transmission system using a vertical layer optimisation technique. A data transmission device predicts the buffer state of a data receiving device by using feedback information of a physical layer, and controls data transmission by referring to the predicted buffer state. The data transmission device can control the transmission of first data and second data such that the buffer state of the receiving device is within a preset range.
