摘要： A signal separating system 1 comprises a frequency conversion element 3, a dynamic filter component 4 with associated coherent stop slot and non-coherent passband, optionally a signal wave enhancer 7 with bypass, and a frequency reconversion element 8. In operation of the system, mixed incoming signals 12 (CW or pulse signals) having known interference and unknown emission components can be effectively separated, permitting a virtually instantaneous separation of the known interference from the unknown emissions and permitting an unobscured monitoring and/or characterisation of the extracted unknown emissions 21, if desired. The arrangement bears definite advantage over known arrangements and retains utility for various frequency/agile or multiple or non-agile unknown signal applications.

摘要： Data from a plurality of sensors representing a patient's condition, including the measurement signals and also secondary parameters derived from the measurement signals, are displayed in a simple way by mapping them from the multi-dimensional measurement space to a two-dimensional visualisation space. This can be achieved using a mapping which preserves the topography of the data points, for instance by ensuring that the inter-point distances in the visualisation space match as closely as possible the corresponding inter-point distances in the measurement space. Such a mapping, for instance Sammon's mapping is achieved by a suitably trained artificial neural network. The parameters are normalised before the mapping process and the normalisation and mapping are such that mapped points from a patient whose condition is normal appear in the centre of the visualisation space, whereas points from a patient whose condition is abnormal appear at the edge of the visualisation space. The artificial neural network may be trained using data points from a single patient or from a group of patients, and data may be thinned out using a pre-clustering algorithm.

摘要： Methods and systems for acquiring a received impulse signal packet including a plurality of repeating short acquisition code sequences and at least one ratchet code sequence following a last one of the plurality of repeating short acquisition code sequences, the repeating short acquisition code sequences defined by a short acquisition code, the at least one ratchet code sequence defined by a ratchet code, and each ratchet code sequence greater in length than each repeating short acquisition code sequence. The method includes the step of concurrently searching the received impulse signal packet for the short acquisition code sequence in accordance with a frame time offset and each of a plurality of acquisition code offsets. The frame time offset is adjusted after each time the short acquisition code sequence is not found during a search. Tracking of the received impulse signal packet is initiated immediately after the short acquisition code sequence is found. The method also includes the step of concurrently searching the received impulse signal packet for a ratchet code sequence in accordance with each of a plurality of code boundaries. A delimeter is then searched for and found. Data payload follows the delimeter. Further, a threshold detector using an acquisition logic algorithm comprising four fully programmable threshold equations is provided herein.

摘要： A device and method is presented in which an adjustment to the noise conditions is made for the purpose of controlling the volume and other variables of a desired signal offered in a monitored space, in the course of which, for the purpose of adjustment, a monitoring signal occurring at the monitoring point is picked up and split into a desired-signal component and a noise-signal component. These two components then become the basis for the adjustment. Also in accordance with an embodiment of the invention, an adaptive warped filter is provided. The adaptive warped filter is used to extract a noise related signal which is then used as part of the basis for the adjustment. In an embodiment, the extracted noise signal is corrected and used to control a dynamic controller which adjusts the volume.

摘要： An apparatus and method for improving the efficiency of a power amplifier operating on the basis of a signal of a large peak-to-average power ratio (PAR). A main amplification part detects envelope values of an input baseband signal, reduces a peak value of the envelope values of the baseband signal to generate a peak reduced signal, amplifies the generated peak reduced signal, and outputs a first amplified signal. An error correction amplification part amplifies an error signal indicating a difference between the baseband signal and the peak reduced signal, and outputs a second amplified signal. A summing part combines the first amplified signal from the main amplification part and the second amplified signal from the error correction amplification part, such that high amplification efficiency is produced and an amplified output signal with reduced spectral regrowth in which an error is corrected can be outputted.
