System Performance of Concatenated STBC and Block Turbo Codes in Dispersive Fading Channels
EURASIP Journal on Advances in Signal Processing, 2005 A new scheme of concatenating the block turbo code (BTC) with the space-time block code (STBC) for an OFDM system in dispersive fading channels is investigated in this paper.

Code designs for MIMO broadcast channels
, 2009 Recent information-theoretic results show the optimality of dirty-paper coding (DPC) in achieving the full capacity region of the Gaussian multiple-input multiple-output (MIMO) broadcast channel (BC).

Bias in, symbolic compliance out? GPT's reliance on gender and race in strategic evaluations
Strategic Management Journal, EarlyView.Abstract Research summary Organizations are increasingly using large language models (LLMs) to support strategic evaluations. We examine whether and how these systems rely on gender and race. We asked GPT to evaluate identical startup pitches varying only the founder's name, shaping gender and race perceptions.

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.

Baselining Large Language Model Performance in Systems Engineering Using SysEngBench
Systems Engineering, EarlyView.ABSTRACT In the rapidly evolving field of artificial intelligence (AI), large language model s (LLMs) have demonstrated impressive capabilities in generating natural language. However, their proficiency in specialized domains, particularly in the field of systems engineering (SE), remains less explored and unquantified.

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
