METHOD AND SYSTEM FOR THE ITERATIVE ENCODING-DECODING OF STREAMS OF DIGITAL DATA ENCODED BY SPATIO-TEMPORAL COMBINATIONS, IN MULTIPLE TRANSMISSION AND RECEPTION

摘要

The present invention relates to a method for encoding a digital data stream coded by the space-time combinations in multiple transmission and reception, and decoding. ; During transmission, the initial stream (IDS) is subjected to an external coding (A), block way interleaving (B), demultiplexing (C) on a plurality of paths, one for Ξ _m inner coding on each path, then space-diversity It is transmitted to a specific antenna of the plurality (ν) to form an array. Upon reception, the coding of the transmitted symbol streams are observed by the receiving antenna of the number of independent (ν) to the number of transmit antenna (F), the observed code symbol stream The equalization and joint decoding (G), deinterleaving (H), the outer decoding (I), through the process of interleaving (J), the turbo-priori information item of the re-injected (K) code bits of the detection process, It generates (api). ; The invention is applicable to the implementation of the universal radio frequency interface, in particular a mobile radio telephone. ; Radio frequency, the mobile radio telephone, interface, decoding, interleaving, symbol, equalization
