Abstract
Improving decoding of a set of k data symbols received from several receivers, the data symbols being encoded by a systematic block error correcting code of dimension k and size n. The set of data symbols is received along with a corresponding subset of parity symbols, forming a partial data block comprising m symbols. A partial data block transmitted by one emitter, comprising a set of k data symbols and a subset of (m−k) parity symbols, is received from each receiver. For each received partial data block, a subset of parity symbols is generated and an item of reliability information is computed as a function of the received parity symbols and parity symbols generated from a received set of data symbols. The items of computed reliability information are compared with each other to select one received set of data bits.
