30 years of the quantum cascade laser by Giacomo Scalari, Jérôme Faist

“…It was January 1994, when the first quantum cascade laser (QCL) displayed laser action in Bell Laboratories. During these 30 years the QCL evolved incessantly, from a lab curiosity to the main on-chip source of coherent radiation in the Mid-IR and THz ranges. …”

Perfect space-time block codes and high performance decoding algorithm by HU Jun-feng1, YANG Yuan1, ZHANG Hai-lin1

“…Based on the structure of perfect space-time block codes（STBC）,an equivalent vertical Bell Laboratories layered space-time（V-BLAST） decoding model was given.Minimum mean-square error decision feedback equalizer（MMSE-DFE） was used to preprocess this model and a decoder with boundary controlled Fano tree search algorithm was proposed.This decoder achieves almost maximum likelihood（ML） decoding performance and applies for any antenna configurations.For a wide range of signal-to-noise ratio（SNR）,the decoder has lower computational complexity than that of previously proposed near-ML decoders.Operating in complex number field,the decoder is robust for any constellations.The decoder can apply for any multi-input multi-output（MIMO） systems that can be transformed into an equivalent V-BLAST model.Simulation results demonstrate the excellent performance of the proposed decoder.…”
