    Stress Recovery Effects of High- and Low-Frequency Amplified Music on Heart Rate Variability by Yoshie Nakajima, Naofumi Tanaka, Tatsuya Mima, Shin-Ichi Izumi

    Published 2016-01-01
    “…To measure autonomic response, we calculated the high-frequency normalized unit (HFnu), low-frequency normalized unit, and the LF/HF ratio from the heart rate using electrocardiography. We defined the stress recovery ratio as the value obtained after participants listened to music following scratching noise, normalized by the value obtained after participants listened to white noise after the stress noise, in terms of the HFnu, low-frequency normalized unit, LF/HF ratio, and heart rate. …”

    Iterative algorithm on single-channel blind separation and decoding of co-frequency modulated signals by LIAO Can-hui, TU Shi-long, WAN Jian

    Published 2011-01-01
    “…An algorithm was proposed to exploit the codes in iterative single-channel blind separation and decoding of two co-frequency modulated signals with long-constraint channel codes.The output log-likelihood ratio(LLR) values of the decoder were used as a prior LLR fed back to the separator to improve the separation performance.Special emphases were laid on soft input soft output blind separation,maximum a posteriori(MAP) decoding and LLR interaction between separator and decoder.Simulation results show that the proposed algorithm can make a significant improvement in per-formance over the algorithms without iterations.For BPSK signals with(2,1,6) convolutional codes and random inter-leaving,a gain of about 2dB in signal-noise ratio can be obtained after two iterations.…”
