Spectrum sensing is a key technology in Cognitive Radio (CR). It is an important function to be performed by every cognitive radio. Either single or multiple users can take part in spectrum sensing process. This paper presents a multiple thresholds cooperative spectrum sensing algorithm based on signal-to-noise ratio (SNR). In the first phase, the cognitive nodes that satisfy the request of double...
Patients infected human papillomavirus (HPV) is increasing all over the world, in particular the community of woman. Microarray-in-a-tube system is a novel method of integrating polymerase chain reaction (PCR) with the microarray technique and a simple and high-throughput detection system. In this work, the microarray-in-a-tube system used in the function of detection human papillomavirus genotypes...
A fast algorithm is proposed to choose the optimal port-combination for the next generation non-phased array coil. This kind of coil is so promising and scalable that it would mimic any known phased array coil at the cost of a combinatorial optimization problem. The raw data of signal and noise are respectively collected using a Siemens Trio 3T scanner according to the Kellman-McVeigh method. The...
In literatures of auditory frequency following response (FFR), it has been suggested that adding the frequency following responses evoked by opposite stimulus polarities can be used to emphasize neural activities related to the stimulus envelope, while subtracting the responses can enhance the activities related to fine structure such as the formants in speech stimuli. To assess the effectiveness...
Speech intelligibility for noise reduction algorithms which were integrated into perceptual wavelet packet-based speech coding strategy in cochlear implant (CI) processors was investigated in this study. The noise reduction algorithms including time-adaptive wavelet thresholding (TAWT) and time-frequency spectral subtraction (TFSS) were selected for this study due to simple and suitable for real-time...
