  • Publication number: 20230335106
    Abstract: Systems and methods are disclosed for identifying at least one cause of noise in a vehicle audio system. The vehicle audio system may include a plurality of audio channels. Acoustic output may be generated and received through each of the audio channels. Acoustic input may be received from one or more of the audio channels and may be processed to generate processed acoustic input. The processed acoustic input may include a frequency response of the acoustic input. The processed acoustic input may be compared to corresponding channel target input and at least one deviation may be determined. A cause of the at least one deviation may then be determined based on a relationship between the at least one deviation and a set of resolved indications of cause, each of the set of resolved indications of cause corresponding to at least one of a set of recorded causes.

  • Patent number: 11751221
    Abstract: Data is scrambled at a transmitter according to one of a number of predetermined scrambling sequences which are associated with a particular one of a number of predetermined transmit antenna diversity schemes (i.e., a specific number of transmit antenna ports). Received data is decoded using one or more of the known transmit antenna diversity schemes and the scrambled data is descrambled according to a corresponding descrambling sequence (related to the scrambling sequence). Based on the descrambled data, the receiver determines which transmit antenna diversity scheme (i.e., the number of antenna ports) is used by the transmitter. In one specific embodiment, CRC parity data is scrambled in the transmitter and the receiver descrambles the recovered CRC parity data according to a descrambling sequence, computes CRC parity data from the received data, and compares the descrambled CRC parity data to the newly computed CRC parity data.
