摘要： A method includes storing at least one user datum received from a user in a secure storage portion of a memory within a mobile communication device. Authentication information is received into the mobile communication device. The at least one user datum is transmitted from the mobile communication device to a recipient in response to entry of the authentication information, while preventing the user of the mobile communication device from reading the at least one user datum.

摘要： Methods and apparatus are provided for block and rate independent decoding of LDPC codes. The disclosed LDPC decoders support multiple code block lengths and code rates, as well as a variable parity check matrix. The disclosed LDPC decoders decode LDPC codes that are based on a parity check matrix having a plurality of sub-matrices, wherein each row and column of the plurality of sub-matrices has a single entry. Each of the sub-matrices has at least one associated Phi-node, wherein each Phi-node comprises a memory device having a plurality of memory elements, wherein one or more of the memory elements may be selectively disabled. The Phi-nodes may be selectively disabled, for example, at run-time. The Phi-node optionally further comprises a multiplexer in order to provide a variable parity check matrix.
