A data communications receiver incorporating soft decision error correction decoding and a means to set the amplitude or threshold for quantized soft decisions in a near-optimum manner to a soft decision decoder. In one embodiment the means for setting the amplitude or threshold measures the soft decisions from a quantizer and marks data bits as weak or strong. The gain or threshold is automatically adjusted to achieve a desired fraction if each marking. The desired fraction is chosen as the value that optimizes performance of the soft decision decoder.

An apparatus and method provides efficient parallel processing for use with a single-bit sampler that provides single-bit samples at a high sample rate. A serial-to-parallel converter converts the single-bit samples into parallel single-bit samples at a reduced sample rate. A digital quadrature mix performs a frequency shift to the parallel single-bit samples and simultaneously performs a real-to-complex conversion of the parallel single-bit samples from the serial-to-parallel converter to provide parallel I and Q output values at an intermediate frequency. The serial-to-parallel converter has shift register stages that provide a memory for use in functional realization of a boxcar filter and decimation-by-two in the digital quadrature mix. The digital quadrature mix utilizes logic to route and invert the parallel single-bit samples resulting in the parallel I and Q single-bit output values. Additional filter and decimate stages may be used to process the parallel I and Q single-bit output values.

The invention is a way to detect and correct data inversions or other phase ambiguities in a modem's data, without incurring a significant penalty in error rate performance, throughput, or overhead, by making a particular use of the error detection and correction (EDAC) code which would typically be used for random errors. The decoder is set up so that the inverted data or out-of-phase data generates a distinctive syndrome which signals to a phase corrector.

FM signals are demodulated with lower distortion and expenditure of less computing time by digitizing the signals using an A/D converter of predetermined sample frequency and down-converting the signals to their base band quadrature components. The quadrature components are delayed by one sample period, and the complex cross-product of current quadrature components and the delayed quadrature components from the immediately preceding A/D sample period is taken. The arctangent of the resulting cross-product is taken by calculating the ratio of the imaginary and real components thereof to produce a value which is representative of the original modulating signal.

Audio beat notes produced by sampling a square wave in a digital quadrature FM demodulator are reduced by adding filtered random noise, or dither, to the signal to be demodulated to randomly vary the width of successive pulses in the square wave. Filtration of the random noise prevents feedthrough of noise which would degrade the demodulated signal.

A device may determine one or more trends by using one or more machine learning techniques to process historical transactional information included in a set of historical transactional documents. The device may receive a set of transactional documents associated with transactions between a client organization and a vendor organization. The device may generate, based on the one or more trends, a first set of exceptions indicating that one or more transactional documents are problematic transactional documents. The device may generate, using a similarity analysis technique, a second set of exceptions indicating that one or more additional transactional documents are duplicate transactional documents. The device may generate a set of claims based on one or more exceptions. The device may perform, based on the set of claims, one or more actions associated with correction or prevention of transaction processing errors relating to the set of transactional documents.
