Configurable encoder for cyclic error correction codes
Apparatus for encoding includes a first processing stage, which is configured to filter input data with a first set of coefficients belonging to a first generator polynomial representing a first ecc, to produce a first output. A second processing stage is configured to filter the first output using a second set of coefficients belonging to a quotient polynomial, which is defined as a quotient of a second generator polynomial, representing a second ecc, divided by the first generator polynomial, to produce a second output.

Spectroscopic apparatus and methods
A method of estimating background radiation in spectral data. The method may comprise, iteratively, fitting an analytical curve, such as a spline curve, to reference data, determining an allowable deviation of the reference data from the analytical curve and clipping data points of the reference data or the spectral data that are more than the allowable deviation above the analytical curve to provide the reference data for the next iteration until termination criterion is met.

Vehicle ambient temperature estimation system
Ambient temperature is determined using a vehicle-implemented system based on an estimated ambient temperature determined in view of a radiator fluid temperature profile. During periods of radiator fan operation, radiator fluid temperature is measured and logged to create the radiator fluid temperature profile.

System and method for wireless communication
A method and system for wireless communication are disclosed. The method comprises: the master device generates a sequence code through a specific encoder and transmits the sequence code to each slave device continuously within a preset period according to the communication demand, wherein the specific encoder is a feedback shift register constructed by a specific polynomial, of which the coefficients and the order are in correlation with the communication demand while all of the coefficients and initial values are not equal to 0 at the same time; the preset period is greater than or equal to the sum of a sleeping period and a detecting period of the slave device, which constitutes a sleeping-and-waking cycle; the slave device receives a continuous section of the sequence code in the detecting period, decodes the sequence code through a decoder corresponding to the encoder, and performs corresponding operation according to the decoding result..

Multiclass classification of points
A method includes obtaining, by executing a module stored on a non-transitory computer-readable storage device, approximately-zero polynomials for each of multiple classes. The method further includes evaluating the approximately-zero polynomials for each class on a plurality of points to compute distances from each point to each of the classes.

Communication apparatus, terminal apparatus and communication method
A loss correction encoding device having an improved capability of loss correction using ldpc-cc includes a rearranging unit that rearranges information data contained in n information packets according to the constraint length kmax and the encoding rate (q−1)/q of a check polynomial of the loss correction code used in a loss correction encoding unit. Specifically, the rearranging unit rearranges the information data in such a way that continuous kmax×(q−1) pieces of information data after rearrangement are contained in different information packets.
