    摘要: A multi-level solid state non-volatile memory array has memory cells that store data using a first number of digital levels. A controller of the memory array encodes a series of data bits to generate a series of encoded data bits, and converts the series of encoded data bits into a series of data symbols. The controller sends, to the memory array, a stored series of data symbols based on the series of data symbols for storage in a memory cell of the multi-level solid state non-volatile memory array. The controller generates an output signal based on data associated with the stored series of data symbols. The output signal is characterized by a second number of digital levels greater than the first number of digital levels. The controller outputs a series of output data symbols based on the output signal.

    摘要: A multiple-input multiple-output (MIMO) transmitter including a scrambler and a forward error correction encoder. The scrambler is configured to receive user data and generate scrambled data in response to the user data. The forward error correction encoder is configured to generate encoded data, in response to the scrambled data, using a low density parity check (LDPC) matrix, wherein the LDPC matrix is derived from a specified base matrix.
