Abstract: The invention relates to the transmitting of a public data to at least a number K of terminals in a wireless communication system employing a MIMO (Multiple Input Multiple Output) scheme, using a set of N pre-coders (Wi). The method includes, based on the N pre-coder (Wi), determining a set of N??N optimized pre-coders (W?i) and, based on the set of N??N optimized pre-coders (W?i), computing N? optimized resource unit quantities T?(i), the N? optimized pre-coders respectively corresponding to the N? optimized resource units quantities T?(i). The method further includes transmitting N? data Di, each of the N? data being a part of the public data, such that, for i=1 to N?, Di is transmitted on T?(i) resource units which are pre-coded onto NTx antennas using the pre-coder W?i.

Abstract: A method for determining features of an error correcting code system, comprising independent error correcting codes and a polarization module, allowing transmitting a binary input vector on block fading sub-channels, the independent error correcting codes generating components of the binary input vector and a channel polarization being applied to the binary input vector by the polarization module. The method comprises: obtaining characteristics of the block fading sub-channels; and, determining features of said error correcting code system, comprising, for each error correcting code, a rate of said error correcting code, adapted to the obtained characteristics and minimizing a function of a probability that an instantaneous equivalent channel capacity of the block fading sub-channels is below a transmission rate transmitted on the block fading sub-channels.
