BACKGROUND The 'broken mirror' theory of autism, which proposes that a dysfunction of the human mirror neuron system (MNS) is responsible for the core social and cognitive deficits in individuals with autism spectrum disorders (ASD), has received considerable attention despite weak empirical evidence. METHODS In this electroencephalographic study, we(More)
In order to improve the bit error rate (BER) of multiple-input multiple-output orthogonal frequency diversity multiplexing (MIMO-OFDM) system in Nakagami-m channels, the model used rate-compatible punctured convolution (RCPC) and space-time block code (STBC) at the transmitter, maximum ratio combining (MRC) at the receiver was put forward. The(More)
With the development of general-purpose processors (GPP) and video signal processing algorithms, it is possible to implement a software-based real-time video encoder on GPP, and its low cost and easy upgrade attract developers' interests to transfer video encoding from specialized hardware to more flexible software. In this paper, the encoding structure is(More)
In order to improve the error resilient ability and transmission efficiency for image transmission over wireless frequency selective fading channels, a joint source-channel coding (JSCC) scheme was proposed. In which, MIMO-OFDM and adaptive wavelet pretreatment were combined together. MIMO-OFDM was used to deal with frequency-selective, time dispersive(More)
3D scene reconstruction of binocular fisheye obstacle camera for lunar rover is challenging. This paper presents a large field of view (FOV) scene reconstruction method based on fisheye lens. To overcome the problems of the large imaging distortion of large FOV fisheye lens and the existence of information loss when converting to perspective image, we(More)
1 1 1. Abstract A robot localization algorithm based on particle filter is presented. Firstly in order to improve the filtering effect and decrease the number of particles needed, one parallel extended Kalman filter is used as the proposal density of particle filter, thus partial observation information will be infused into the filtering process. Secondly,(More)
