Intelligent medical record input platform based on knowledge base

The invention relates to an intelligent medical record input platform based on a knowledge base. The knowledge base needed by medical record input is formed through carrying out information extraction on history medical records of a hospital, and a specific operating procedure is as follows: (1) electronic medical records are uploaded to a background business management module; (2) the background module automatically scans and extracts corpora and medical record examples from the electronic medical records in batch to form the knowledge base; (3) an intelligent medical record input module downloads the generated knowledge base from a server side, and a user utilizes an intelligent medical record input client to input the medical record; and (4) the user triggers a client function key to send the current input information to the background to carry out query of related factors of the medical record to give a diagnosis prompt. According to the intelligent medical record input platform based on the knowledge base, the user selects words or sentences with highest accuracy to quickly input the medical record in a minimum context based on the knowledge base formed through carrying out information extraction on the history medical records of the hospital, and an auxiliary diagnosis information prompt function is provided for the user in the input process, and the intelligent medical record input platform is convenient to use.

Carrier synchronizer for demodulating low signal-to-noise ratio burst signals

The invention discloses a carrier synchronizer for demodulating low signal-to-noise ratio burst signals. The carrier synchronizer comprises an input cache module, an initial frequency deviation estimation module, a frequency deviation partition preset module, N two-way capture tracking modules, N unwrapping phase ambiguity and soft de-mapping modules, an iterative decoding module and an optimal judgment module. Each two-way capture tracking module corresponds to one unwrapping phase ambiguity and soft de-mapping module. Initial frequency deviation is estimated based on preceding heads of the burst signals, then, after an initial frequency deviation estimation result is preset in a partition mode, two-way capture tracking is utilized to conduct carrier synchronization, the optimal judgment module selects an optimal carrier to conduct synchronous output according to judgment soft information statistical values output by the iterative decoding module, and eventually the iterative decoding module conducts decoding on the carrier and outputs a final result. By the adoption of the carrier synchronizer, optimization design is conducted on burst signal carrier synchronization under the low signal-to-noise ratio, and the problem of low signal-to-noise ratio carrier synchronization of TDMA system communication is solved.

Non-data aided OQPSK (Offset Quadra Phase Shift Keying) signal closed loop carrier synchronization method

The invention provides a non-data aided OQPSK (Offset Quadra Phase Shift Keying) signal closed loop carrier synchronization method. The square spectrum characteristics of an OQPSK signal are utilized, a square spectrum estimation based carrier frequency offset coarse estimation algorithm is adopted, and accordingly the range of the frequency of the signal can be effectively reduced. A carrier synchronization loop is of a dot product and cross product frequency discriminator and phase discriminator combined cross ring structure and accordingly the speed and the accuracy of the carrier synchronization can be ensured simultaneously. A proportional integral filter is adopted as a loop filter to enable the synchronization loop to be a second-order loop and accordingly the stable loop dynamic response can be implemented under the conditions that the direct current gain is infinite and the frequency offset is a constant. According to the non-data aided OQPSK signal closed loop carrier synchronization method, the frequency offset can be accurately estimated, the accuracy and the speed of the carrier synchronization can be ensured, and the recruitments of a communication system can be met through the combined utilization of a dot product and cross product frequency discriminator and phase discriminator on the basis of the square spectrum frequency offset coarse estimation.

Carrier and clock combined synchronization method for OQPSK modulation

The invention provides a carrier and clock combined synchronization method for OQPSK modulation. The method comprises the following steps of: performing coarse estimation on carrier frequency by use of the cyclic spectrum characteristic of an OQPSK signal; performing series expansion on the error function of a COSTAS loop and simplifying the error function; and estimating the residual carrier frequency offset based on the maximum likelihood principle, and meanwhile, estimating the clock.
