We investigate turbo coded bit interleaved coded modulation (BICM) schemes for multiple-input multiple-output (MIMO) block-fading channels. Both serial and parallel concatenated turbo codes are considered and their performance is compared. A sphere decoder is employed to achieve good performance with reduced computation complexity when the size of the constellation or the number of transmit antenna is large. Simulation results are provided to demonstrate the effectiveness of the proposed schemes in MIMO block-fading channels.
