    Abstract: PURPOSE: A transmission device for a hierarchically modulated signal and a method thereof are provided to improve the reception performance of a second layer signal by applying a phase rotation technology to the second layer signal. CONSTITUTION: A terrestrial-digital multimedia broadcast (T-DMB) transmitter comprises a basic layer symbol generator (110), a hierarchical modulator (134), and an enhanced layer symbol generator (140).
