A channel-coding scheme is introduced that features parallel concatenated recursive systematic codes with multilevel modulation and multiple transmit/receive antennas. The proposed scheme is a type of turbo space-time codes and is referred to as turbo multiple antenna coded modulation (turbo-MACM). Turbo-MACM combines the advantages of powerful turbo codes with the transmit/receive diversity of multiple antenna coded modulation. The scheme utilizes recursive and systematic constituent codes and features full rate and, as demonstrated by simulations, full spatial diversity. An iterative symbol-by-symbol maximum a posteriori (MAP) algorithm operating in the log domain is developed for decoding turbo-MACM. Simulation results are provided for 4-PSK and 8-PSK schemes over the block-fading channel. It is shown that the scheme provides an advantage of 3 to 5 dB over conventional space-time codes of comparable complexity.
