Abstract
A telecommunication method which includes: mapping, with a mapper, input data to points of a constellation in order to generate symbols, repeating symbols according to a pattern, modulating the symbols, with a modulator, in order to generate multi-carrier symbols, and transmitting a radio signal representative of the multi-carrier symbols.
Claims20
A telecommunication method comprising:
- encoding data at a rate r1 with a binary encoder;
- mapping the encoded data with a mapper to points of a constellation in order to obtain symbols;
- performing a multi-carrier modulation with a modulator with N sub-carriers, which maps the obtained symbols to the N sub-carriers to generate multi-carrier symbols;
- transmitting the multi-carrier symbols;
- and
- repeating symbols of the obtained symbols in order to obtain several occurrences of a same symbol before mapping the obtained symbols to the N sub-carriers of the modulator and in order to map several occurrences of the same symbol to several sub-carriers respectively.

A reception method comprising:
- demodulating a received multi-carrier symbol in order to estimate symbols of a constellation mapped to the multi-carriers, such that multiple occurrences of a same symbol are respectively mapped to multiple carriers;
- averaging the multiple occurrences of the same symbol in order to improve estimation of the symbol;
- demapping the symbols in order to estimate data mapped to these constellation symbols;
- and
- decoding the data.

A telecommunication equipment comprising:
- a binary encoder of rate r1;
- a mapper for mapping input data to points of a constellation and for generating symbols;
- a modulator with N sub-carriers for modulating a block of N symbols made up of L occurrences of L symbols, respectively, and at least one other occurrence of at least one of the L symbols, with all the L occurrences and other occurrences defining a new rate r2=r1×L/N, for generating multi-carrier symbols;
- and
- a transmitter for transmitting a radio signal representing the multi-carrier symbols.

- derepeater for averaging the multiple occurrences of the same symbol and for improving the estimation of this symbol;
- demapper for demapping L constellation symbols and estimating data mapped to these L constellation symbols, 0<L<N;
