  • Publication number: 20240121028
    Abstract: The present disclosure discloses a data receiving apparatus and a data receiving method having blind deconvolution mechanism. A descrambling circuit descrambles received data according to an antenna assumption and N data position assumptions within a transmission period to generate N groups of soft-bit data. A soft-bit processing circuit retrieves bit position data to determine non-variable bit positions and variable bit positions. N circular buffers of a storage circuit store and superimpose the N groups of soft-bit data corresponding to N data position assumptions in a circular manner to generate N groups of superimposed results and keep the data corresponding to the non-variable bit positions. A post-processing circuit performs de-interleaving and decoding on the N groups of superimposed results to generate N groups of decoded results to perform redundancy check thereon. When one decoded results passes the redundancy check, the soft-bit processing circuit stops performing the blind deconvolution process.

  • Publication number: 20220116140
    Abstract: The present invention discloses a data decoding circuit. A data reforming circuit receives encoded data encoded by using tail-biting convolutional code to identify a first unknown bit section, a known bit section and a second unknown bit section in an order to further connect the second unknown bit section and the first unknown bit section in series to generate data to be decoded. A decoding circuit decodes the data to be decoded by using Viterbi algorithm and at least one piece of known bit information to generate a decoded result that includes a second decoded bit section and a first decoded bit section respectively corresponding to the second unknown bit section and the first unknown bit section. A data restoring circuit connects the first decoded bit section, a known decoded bit section corresponding to the known bit section and the second decoded bit section in series to generate decoded data.

  • Publication number: 20190176295
    Abstract: A vacuum absorbing platform, having contiguously a base and a plate unit disposed on the base and having a body, a front panel and a rear panel. The body has a plurality of cells contiguous with each other and a plurality of first openings configured on the walls of the cells. The front panel is secured on one side of the body to seal the cells and has a plurality of voids communicate with the cells respectively. The rear panel is secured on the other side of the body to seal the cells. A plurality of adjusters are located between the base and the plate unit to regulate the distance therebetween.
