Abstract: An integrated GNSS signal having a plurality of signal components with arbitrary power allocation may be processed. In an embodiment, an integrated signal processing unit of a GNSS receiver may generate in parallel complex rotated samples for a sample of the integrated signal. The complex rotated samples (e.g., early and late complex rotated samples) may be accumulated in parallel in a window that spans any arbitrary width that is less than or equal to a number of code chips in a PRN code sequence. In an embodiment, the integrated signal processing unit may sequentially generate complex rotated samples for the sample. The complex rotated samples (e.g., early, punctual, and late complex rotated samples) may be sequentially accumulated in the window. The GNSS receiver may utilize the accumulated complex rotated samples to perform correlation techniques, perform multipath mitigation techniques, and/or track the integrated signal.

Abstract: A device may receive a PDCCH signal, may decode encoded bits of the PDCCH signal to generate coded bits, may reencode the coded bits, and may calculate a detection error probability of each coded bit at an output of soft demodulation. The device may calculate a channel decoding error probability that cyclic redundancy check bits are still attached to the coded bits, and may calculate an error probability of channel reencoding, of each coded bit, due to error propagation of polar decoding and reencoding. The device may calculate a probability density of a BMR associated with the coded bits, and may calculate a threshold based on the detection error probability, the channel decoding error probability, the error probability of channel reencoding, and the probability density of a BMR. The device may determine that the PDCCH signal is invalid based on the BMR being greater than the threshold.

Abstract: The method of manufacturing a magnetic rotor unit comprises providing a composite magnetic rotor body. The composite magnetic rotor body comprises magnetic particles dispersed in a polymer resin. The composite magnetic rotor body has a hole. The method further comprises inserting a shaft into the hole. The outer diameter of the shaft corresponds to the inner diameter of the hole. The method further comprises heating of the shaft.

An apparatus for such manufacture, and a magnetic rotor unit manufactured by such method, are also provided. Such rotor units have wide application, and may for example be used in sensors, electromagnetic generators, pulse generators, motors, magnetic brakes and magnetic couplings.
