Sphere-Packing Modulated Space-Time Coding Using Non-Binary LDPC-Coded Iterative-Detection
, 2008 A recently proposed Space-Time Block Coding (STBC) signal construction method that combines orthogonal design with sphere packing, referred to here as (STBC-SP), has shown useful performance improvements over Alamouti’s conventional orthogonal design. In

Pest Management Science, EarlyView.Experimental setup for dsRNA feeding in Brassicogethes aeneus to evaluate the effect of a synthetic polymer nanocarrier on RNAi efficiency. The experiment assessed whether the nanocarrier enhances RNAi after oral dsRNA delivery. (a) Stability of dsRNA–nanocarrier complexes was tested in simulated gut conditions. (b) Gene expression of αCOP and dre4 was

Frequency-Domain Turbo Equalisation in Coded SC-FDMA Systems: EXIT Chart Analysis and Performance [PDF]
, 2012 In this paper, we investigate the achievable performance of channel coded single-carrier frequency division multiple-access (SC-FDMA) systems employing various detection schemes, when communicating over frequency-selective fading channels.

Advances in Electrical and Computer Engineering, 2011 This paper analyzes the extrinsic information scaling coefficient influence on double-iterative decoding algorithm for space-time turbo codes with large number of antennas. The max-log-APP algorithm is used, scaling both the extrinsic information in the

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

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.
