Concatenated space-time block codes and TCM, turbo TCM, convolutional as well as turbo codes [PDF]
Globecom '00 - IEEE. Global Telecommunications Conference. Conference Record (Cat. No.00CH37137), 2002 Space-time block codes provide substantial diversity advantages for multiple transmit antenna systems at a low decoding complexity. We concatenate space-time codes with convolutional codes (CC), turbo convolutional codes (TC), turbo BCH codes (TBCH), trellis coded modulation (TCM) and turbo trellis coded modulation (TTCM) schemes for achieving a high ...

Short Low-Rate Non-Binary Turbo Codes [PDF]
, 2012 A serial concatenation of an outer non-binary turbo code with different inner binary codes is introduced and analyzed. The turbo code is based on memory-1 time-variant recursive convolutional codes over high order fields.

Near-Capacity Transceiver Design Using Exit-Curve Fitting: Three-Stage Turbo Detection of Irregular Convolutional Coded Joint Sphere-Packing Modulation and Space-Time Coding [PDF]
, 2007 Conventional two-stage turbo-detected schemes typically suffer from a Bit Error Rate (BER) floor, preventing them from achieving infinitesimally low BER values, especially, when the inner coding stage is of non-recursive nature.

Block turbo codes for space-time systems
Globecom '00 - IEEE. Global Telecommunications Conference. Conference Record (Cat. No.00CH37137), 2002 Advances in the field of information theory have shown that wireless systems using multiple transmitters and multiple receivers can significantly improve the spectral efficiency. Systems using transmit and receive diversity associated with coding such as space time trellis codes have since been developed.
