Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of transmitting broadcast signals, the method comprising: encoding PLP (Physical Layer Pipe) data according to a code rate; bit interleaving the encoded PLP data; demultiplexing the bit interleaved PLP data into first data cells and second data cells; mapping the first data cells onto first symbols in a first NUC (Non-Uniform Constellation), and mapping the second data cells onto second symbols in a second NUC; MIMO (Multi-Input Multi-…
