Abstract
A data transmission method implemented by a first item of telecommunication equipment transmitting to a second item of telecommunication equipment. The method includes: encoding input data by using an encoder; and puncturing data after encoding; modulating with mapping of the data, after puncturing, on one of M symbols of a constellation having order M, where M=2q, q>=2. The method is such that the puncturing of the data differs according to the position of the symbol in the constellation on which these data are mapped after puncturing.
Claims20
A data transmission method, implemented by a first equipment, for transmitting data to a second telecommunications equipment, comprising:
- coding input data by using an encoder,
- puncturing the data after coding,
- modulation, with mapping of the data after puncturing onto a symbol from among M symbols of a constellation of order M, M=2q q>=2,
- wherein the puncturing of the data is different depending on a position of the symbol in the constellation onto which these data are mapped after puncturing.
A method for communication between a first equipment and a second telecommunications equipment, wherein the method is implemented by the second telecommunications equipment and comprises:
- receiving a data signal, data of the data signal being mapped before transmission onto symbols of a constellation of order M, M=2q q>=2,
- demodulating the symbols with demapping of the data,
- depuncturing the data after demapping of the data, wherein a puncturing of the data at transmission is different depending on a position of the symbol in the constellation onto which these data are mapped after puncturing, and
- decoding the data after depuncturing.
A telecommunications equipment to communicate with a second equipment wherein the telecommunications equipment comprises:
- at least one computer;
- and
- at least one non-transitory computer readable medium comprising instructions stored thereon which when executed by the at least one computer configure the telecommunications equipment to perform a method comprising:
- coding input data,
- puncturing the data after coding,
- modulating the data after puncturing by mapping the data after puncturing onto a symbol from among M symbols of a constellation of order M, M=2q q>=2,
- wherein the puncturing of the data is different depending on the position of the symbol in the constellation onto which these data are mapped after puncturing.
A telecommunications equipment to communicate with a first equipment in order to receive a data signal, data of the data signal being mapped before transmission onto symbols of a constellation of order M, M=2q q>=2, wherein the telecommunications equipment comprises:
- at least one computer;
- and
- at least one non-transitory computer readable medium comprising instructions stored thereon which when executed by the at least one computer configure the telecommunications equipment to perform a method comprising:
- demodulating symbols with demapping of the data,
- depuncturing the data after demapping of the data, puncturing of the data at transmission being different depending on a position of the symbol in the constellation onto which these data are mapped after puncturing, and
- decoding the data after depuncturing.
