A class of soft-input soft-output demodulation schemes for multiple-input multiple-output (MIMO) channels, based on the sequential Monte Carlo (SMC) framework under both stochastic and deterministic settings. The stochastic SMC sampler generates MIMO symbol samples based on importance sampling and resampling techniques, while the deterministic SMC approach recursively performs exploration and selection steps in a greedy manner. By exploiting the artificial sequential structure of the existing simple Bell Labs Layered Space Time (BLAST) detection method based on nulling and cancellation, the proposed algorithms achieve an error probability performance that is orders of magnitude better than the traditional BLAST detection schemes while maintaining a low computational complexity. Performance is comparable with that of the sphere decoding algorithm, with a much lower complexity. Both the stochastic and deterministic SMC detectors can be employed as the first-stage demodulator in an iterative or turbo receiver in coded MIMO systems.

The invention relates to an electrocardiogram classification method based on convolutional neural network and long-term and short-term memory network. An arrhythmia automatic classification method isrealized by multi-lead electrocardiogram data and a convolutional neural network and long-term and short-term memory network (CNN-LSTM) combined model. On one hand, compared with single-lead electrocardiogram, the multi-lead electrocardiogram contains more information, and on the other hand, the CNN-LSTM combined model combines the advantages of CNN and the advantages of LSTM. The electrocardiogram classification method has unique advantages in the respect of studying the spatial data structure and the time sequential structure. The multi-lead electrocardiogram data is used for training the CNN-LSTM, so that the learning efficiency of the network and the electrocardiogram recognizing precision can be improved.

The invention discloses a compression imaging system based on a separated two-dimensional compression sensing principle. With the adoption of the imaging system, a sequential structure is adopted to produce an image on a digital micro-mirror device (DMD) through a focusing lens; line information of the image is treated by controlling a micro-mirror angle of the DMD through a constructed random line measurement matrix; the obtained line information is focused on a linear CMOS (complementary metal-oxide-semiconductor transistor) image sensor through a micro-mirror array; column information of the image is processed by means that the CMOS sensor is controlled to carry out pixel read by the constructed random column measurement matrix, so that a primary imaging process is realized, and compression information of the image is obtained through an imaging process with a certain frequency, so that the entire compression imaging process can be completed. The compression imaging system has the advantages of rapid imaging speed and strong anti-jamming capability and can provide a new method for imaging in a severe environment and imaging in an encrypted manner.

An electromechanical transient simulation modeling method of a direct-drive wind generating set is provided. A model consists of eight modules which are relatively independent in order to facilitate modular programming. The feedback quantity of each module uses a value at a last moment so that respective modules can be programmed according to sequential structure. In a simulation timing sequence process, two current converter modules are subjected to the dq axis fully decoupled assumption so that the d axis and q axis can be independently modeled. In addition, in order to correctly reflect the fault characteristics of a wind driven generator, a low voltage ride through (LVRT) control strategy is used in the corresponding module. In the simulation timing sequence process, a simulation technique combining large and small steps is used so that the rapid dynamic inside the wind driven generator can be accurately reflected. The method solves the problem that an electromechanical transient model of the wind driven generator cannot completely and accurately reflect the transient process of the wind driven generator.
