摘要： A system and method for storing and retrieving a sparse matrix from memory of a computing device while minimizing the amount of data stored and costly jumps in memory. The computing device may be an FPGA having memory and processing elements. The method comprises storing non-zero data elements of the matrix in a data array and storing their corresponding column address values in a column index array. To read this stored data from memory, each preceding value of the column index array may be compared with each current value of the column index array to determine if the data array value corresponding with the current column index array value belongs on the next row of the matrix. The method may include pre-ordering the matrix with zero-pad placeholders or creating a row increment pointer array which typically stores fewer values than the number of rows in the matrix.

摘要： A finite impulse response filter comprises an input formatter, a plurality of sample registers, a plurality of coefficient registers, an arithmetic unit, a multiply accumulate unit, a crosspoint switch, an interpolator, a control unit, and an output formatter. The input formatter separates the in-phase portion of a complex-number discrete-time sample from the quadrature portion. The sample registers store a plurality of discrete-time samples. The coefficient registers store a plurality of coefficients. The arithmetic unit adds two of the discrete-time samples to create a sum. The multiply accumulate unit includes a multiplier that multiplies the sum by a coefficient to create a product, an adder that adds the product to a sum of products, and a register that stores the sum of products. The crosspoint switch allows communication between the first and second plurality of registers and the arithmetic unit and the multiply accumulate unit. The interpolator inserts a desired number of zeros into the time-sampled data stream to adjust the time-sampled data stream to an increasing sampling rate. The control unit controls the settings of the crosspoint switch, the arithmetic unit, and the multiply accumulate unit. The output formatter combines the in-phase sum of products and the quadrature sum of products to create a filtered complex-number discrete-time sample.

摘要： Improved spur reduction architectures that improve linearity in direct radio frequency (RF) receiver architectures. Non-uniform sampling in the form of sampling clock phase (or frequency) modulation is used to induce phase (or frequency) modulation on signals that are being received from a given Nyquist zone. At the output of the ADC (analog-to-digital converter), the signals are de-modulated to remove the induced modulation based on the Nyquist zone that is being received. The de-modulation process results in non-desired spurious artifacts (interfering leakage signals and ADC spurs) being spread in the frequency domain. Strong spurious artifacts may be removed after measuring the induced modulation and de-modulating. For the case of weak spurious artifacts, the de-modulation for the desired Nyquist zone spread these signals in the frequency domain. Induced modulation on signals may also provide a dithering effect on the ADC.

摘要： Interferometric angle-of-arrival (AOA) ambiguities due to local multipath reflections are resolved by measuring the received phase differences of one or more pairs of antenna elements of the interferometer array, constructing hypotheses from unwrapped phase pairs that correspond to potential AOA solutions, and selecting the hypothesis that most likely represents the true AOA of the signal emitter based on processed unwrapped data that has been corrected through the application of a priori calibration terms selected on the bases of the candidate hypotheses.

摘要： Systems and methods are disclosed that provide ultra-wideband frequency hopping spread spectrum (UWB-FHSS) solutions for transmit and receive architectures. These UWB-FHSS transmit and receive architectures can transmit signals over an extremely wide bandwidth while using a relatively slow analog-to-digital converter (ADC) without suffering from unacceptable performance degradation. For example, ADCs can be used having sample rates lower than standard Nyquist criteria would require for the bandwidth of the spread spectrum utilized.

摘要： An extensible binary mark-up language is disclosed that is compatible with existing XML standards yet provides significantly improved efficiencies for XML-based data storage and communications, particularly for narrow and low bandwidth communication media. A corresponding extensible non-binary mark-up language is also disclosed that is compatible with the XML standard. This dual-representation common message format (CMF) allows standard XML tools to be utilized in viewing and editing XML-based data and allows a CMF parser to be utilized to convert the XML formatted information into an extensible binary representation for actual communication through a medium or storage on a wide range of media. Advantages include a very compact, yet flexible and extensible binary data representation (CMF-B) for a corresponding extensible mark-up language (CMF-X), a data packaging scheme that allows for the effective transport of XML-based data over existing data channels, including narrow-bandwidth channels that utilize existing network protocols, and a CMF parser that allows for seamless conversion between CMF-B and CMF-X.
