    • A device for mapping code words to layers in a Multi-Input Multi-Output (MIMO) system, and for generating layer mapping patterns that include a mapping step, wherein each code word of multiple code words is mapped by mapping different code words of the multiple code words to different layer pairs of L layers on each symbol of multiple symbols, each layer pair is composed of two layers of the L layers, wherein L=2M and M is an integer that is larger than 1; in the method, each code word is circularly mapped on the multiple symbols to all layer pairs that can be generated by the L layers. Accordingly, the diversity performance can be improved through mapping each code word circularly on the multiple symbols to all layer pairs that can be generated by the multiple layers, thus the decoding performance is improved.
