Method for transmitting data that is uniformly distributed in a MIMO telecommunication system

摘要

The present invention relates to a method for transmitting data by means of Nt transmitting antennas over comunication channels featuring Ni inputs. The method according to the invention includes a bit interleaving step involving: bit demultiplexing DMXS, sequence interleaving SRIS, sequence storing and segmenting, segment permutation SPS, and sequence allocation ALS for forming groups G1, G2 of Nt permutated bit sequences Psqj intended to be transmitted through Nt channels allocated to a same bit rank for all transmitting antennas. The invention ensures an essentially homogeneous distribution of the encoded data bits over the different channel inputs, and thus favours data diversity.
