Abstract

See full text

A method for transmitting broadcast signals in a transmitter includes encoding data for Physical Layer Pipes (PLPs), mapping the encoded data onto constellations according to modulation types, multi-input multi-output (MIMO) processing the mapped data for the MIMO processing by multiplying a rotation matrix with a pair of symbols of the mapped data and applying a phase rotation matrix to the multiplied symbols, time interleaving the MIMO processed data, building frames by mapping the time interleaved data, frequency-interleaving data in the built frames, modulating the frequency-interleaved data by an Orthogonal Frequency Division Multiplexing (OFDM) scheme, and transmitting the broadcast signals including the modulated data. The frames includes signaling information for signaling data in the frames. The signaling information includes information on a PLP identifier.
