摘要： The transmitter (1) transmits signals in the form of symbols to a receiver (2). The received signals are analyzed and a probability density function estimate is formed in a pdf estimating means (4). There is a memory means (5) which contains a library of known probability density functions. A comparison means (6) compares the measured histogram from the pdf estimating means (4) with those stored in the memory means (5). The comparison means (6) produces an index (8) which uniquely identifies the library pdf most closely matching the measured pdf. The index (8) is fed back. At the transmitting end of the communication link the index (8) is used to select the corresponding pdf from memory means (7). Memory means (7) and memory means (5) are equivalent. The pdf extracted from memory means (7) is used to adjust the transmission parameters of the system.

摘要： A method of assessing a link for a digital communication system and providing a value for a channel or link state parameter, particularly bit error rate, and apparatus for the same, in which an estimate of the probability density function for the channel or link is obtained by categorising decision variables into threshold categories, and comparing the estimated probability density function with stored known probability density functions. With each stored probability density function the value of the channel parameter being monitored is stored. The value of the channel parameter being monitored is determined by selecting the value associated with the stored probability density function closest resembling the estimated probability density.

摘要： A pattern recognition system for using an artificial neural network architecture that is capable of using its memory to selectively attend to and recognise a learned pattern even when that pattern is embedded in a complex or noisy background. The proposed neural network is used for advanced signal processing in pattern recognition problems that are too difficult or not possible to be solved by the traditional approaches of artificial intelligence and engineering. The pattern recognition system has a neural network architecture consisting of at least two layers in communication with each other, the first layer being a memory layer and having means to store a plurality of memory fields, the second layer adapted to receive an external input and comprising a modulation means that modulates said external input to produce a modulated signal, a comparison means that compares the memory fields of the memory layer with the modulated signal and amplifies those portions of the modulated signal that are located in the memory fields thereby producing an indicator of a match between the memory field and the modulated signal.

摘要： A method of estimating missing data points at known positions in an input signal comprises the steps of: a) Fourier transforming the input signal from one of the frequency or time domains to the other; b) setting a threshold in the other domain so as to separate at least one unambiguous component of the transformed signal from the remaining components including noise; c) inverse Fourier transforming the separated component back to the original domain; d) replacing the missing data points at the known positions in the input signal with data comprising the values of the inverse Fourier transformed separated components at the known positions to generate an improved signal. The steps (a) to (d) are iterated to achieve a desired level of input signal improvement.

摘要： An apparatus (10) for generating one or more radar return signals representative of one or more remote objects useable in ground based, shipboard and airborne radar systems (16) for testing the radar and its user. The apparatus may generate one or more return signal scenarios which may if required interact with the real or preprogrammed movement of the craft in which the radar (16) is fitted. To ensure accurate and repeatable radar return signal generator apparatus (10) operation, the radar's own built-in test signal (21) output is used by the apparatus to calibrate the radio frequency portion of the apparatus which adapts a remote object return signal scenario into the crafts radar device (16). To further improve the accuracy of the return signal a digital first-in-first-out (FIFO 32) delay means is used to accurately allow the delayed reuse of the radar's own transmission signal.
