Turbo coded modulation for wireless communications with antenna diversity
Journal of Communications and Networks, 2000 We introduce turbo coded modulation for wireless communication systems with transmit and receive antenna diversity. We describe a simple way of applying turbo coded modulation to multiple antenna systems. We present examples to illustrate the performance of the turbo coded modulation scheme and observe significant performance gains over the ...

An Efficient Application of Turbo Coding for OFDM In-Phase/Quadrature Index Modulation
IEEE Access, 2023 We present a method to efficiently apply turbo coding to OFDM in-phase/quadrature index modulation (OFDM-IQ-IM) for both cases of presence and absence of puncturing.

Improving the performance of BICM-ID and MLC systems with different FEC codes [PDF]
Advances in Radio Science, 2013 In bandwidth limited communication systems, the high data rate transmission with performance close to capacity limits is achieved by applying multilevel modulation schemes in association with powerful forward error correction (FEC) coding, i.e.

Coded modulation scheme employing turbo codes
Electronics Letters, 1995 The authors present a turbo coding scheme for bandwidth-efficient modulation that outperforms turbo coding with Gray mapping by employing Ungerboeck codes as component codes. The scheme can be decoded iteratively and achieves very good bit error rates at low signal to noise ratios after a small number of iterations. 8PSK is used as an example, although

Nonlinear Turbo Codes for Higher-Order Modulations [PDF]
2008 IEEE International Conference on Communications, 2008 Parallel concatenated trellis coded modulation (PC- TCM) has been traditionally designed using parallel concatenated convolutional codes with a bits-to-symbol mapper. However, this paper shows that for higher-order modulations using linear codes is too restrictive.
