Abstract
The present invention provides a method of transmitting broadcast signals. The method includes, formatting input streams into Data Pipe, DP, data; Low-Density Parity-Check, LDPC, encoding the DP data according to a code rate; bit interleaving the LDPC encoded DP data; mapping the bit interleaved DP data onto constellations according to one of QAM (Quadrature Amplitude Modulation), NUQ (Non-Uniform QAM) or NUC (Non-Uniform Constellation); Multi-Input Multi-Output, MIMO, encoding the mapped DP data by using a MIMO encoding matrix having a MIMO encoding parameter; building at least one signal frame by mapping the MIMO encoded DP data; and modulating data in the built signal frame by an Orthogonal Frequency Division Multiplexing, OFDM, method and transmitting the broadcast signals having the modulated data.
