Rank modulation for flash memories
(United States. Patent and Trademark Office, 2012-08-14)
We investigate a novel storage technology, Rank Modulation, for flash memories. In this scheme, a set of n cells stores information in the permutation induced by the different charge levels of the individual cells. The ...
Low density parity check decoder for irregular LDPC codes
(United States. Patent and Trademark Office, 2013-10-08)
A method and system for decoding low density parity check (“LDPC”) codes. An LDPC decoder includes a control unit that controls decoder processing, the control unit causing the decoder to process the blocks of a low density ...
Source-channel approach to channel coding with side information
(United States. Patent and Trademark Office, 2011-09-13)
Code designs for channel coding with side information (CCSI) based on combined source-channel coding are disclosed. These code designs combine trellis-coded quantization (TCQ) with irregular repeat accumulate (IRA) codes. ...
Low density parity check decoder for regular LDPC codes
(United States. Patent and Trademark Office, 2013-01-22)
A method and system for decoding low density parity check (“LDPC”) codes. An LDPC decoder includes an R select unit, a Q message first-in first-out (“FIFO”) memory, and a cyclic shifter. The R select unit provides an R ...
