Abstract
The present invention provides a method of transmitting broadcast signals. The method includes, processing input streams into plural PLPs; encoding data of the each PLPs according to code rates, wherein the encoding data of the each PLPs further includes, encoding data of at least one PLP with LDPC codes, bit interleaving the LDPC encoded data of the PLP, mapping the bit interleaved data onto a set of constellations according to the code rate, MIMO encoding the mapped data, and time interleaving the MIMO encoded data; building at least one signal frame by mapping the encoded data of the each PLPs; and modulating data in the built signal frame by OFDM method and transmitting the broadcast signals having the modulated data, wherein the bit interelaved data of each PLPs are mapped by using either QAM, NUQ, or NUC.
