  • Patent number: 11133854
    Abstract: Digital predistortion (DPD) arrangements that use coding to differentiate between contributions from individual power amplifiers (PAs) is disclosed. When used with a phased antenna array having N antenna elements and N corresponding PAs, the arrangements may sequentially apply N codes to input signals provided to N PAs. Each code is a vector having N elements, where each element corresponds to a different PA in that the element is a complex gain applied to an input signal for the PA. Together, the N codes may be arranged as N rows or N columns of a matrix P. The disclosed arrangements may generate N feedback signals by applying the matrix P to a signal generated by a probe antenna element sensing wireless RF signals transmitted by the N antenna elements, and to update DPD coefficients based on the N feedback signals. The N codes may be either orthogonal or non-orthogonal.

  • Patent number: 11128314
    Abstract: Techniques related to improving a performance related to at least data reads from a memory are described. In an example, data is stored in a block of the memory as codewords. A data read includes a determination of whether each bit from a portion of the block is a zero or a one based on voltage measurements. Prior to decoding the codewords by performing a decoding procedure by an ECC decoder of the memory, a first number of errors “E01” and a second number of errors “E10” are estimated, where the first number of errors “E01” is associated with bits each being a true zero and erroneously determined as a one, and where the second number of errors “E10” associated with bits each being a true one and erroneously determined as a zero. Thereafter, the decoding of the codewords based on the decoding procedure is performed.
