This contribution proposes a new spatial mapping technique for bit-interleaved coded modulation (BICM) over multiple-input multipleoutput (MIMO) channels. It is an extension of conventional BICM whereby the serial-to-parallel converter is replaced with a more general mapping strategy. Genie performance analysis of spatial mapping schemes results in very simple design criteria for the mapping function. Using an iterative detector, a significant performance gain is observed compared to a
