Transmission method and system using an adaptive and programmable hierarchical modulation
First Claim
Patent Images
1. A method for transmission of a signal including simultaneously a first stream of binary data and one or more other streams of binary data, leading to N binary data streams, N being an integer with a minimum value of 2, the method comprising, in the following order:
- dynamically injecting some bits of a binary data stream in the N binary data streams that are exchanged with some bits of another binary data stream to dynamically produce N separate binary data streams having some bits exchanged with each other as compared to original bits in the first stream and the one or more other streams of said binary data, N being an integer with a minimum value of 2;
coding the dynamically produced data stream bits of the N separate binary data streams after said injection individually using an N number of coders, respectively, to produce N intermediate streams having coded bits, respectively, N being an integer with a minimum value of 2;
dynamically routing the coded bits of said N intermediate streams between N hierarchical levels of a modulator such that some coded bits of a coder in the N number of coders are exchanged with some coded bits of another coder in the N number of coders prior to said routing; and
hierarchically modulating the routed coded bits using the modulator.

Abstract
A method for transmission of a signal simultaneously including a first stream of binary data and one or more other streams of binary data, the method including, in the following order: dynamic distribution of bits of the data streams between coders, with one coder per data stream; coding the distributed bits using the coders; dynamic distribution of the coded bits between hierarchical levels of a modulator; and hierarchical modulation using the modulator.
