Systems and methods for generating check node updates in the decoding of low-density parity-check (LDPC) codes use new approximations in order to reduce the complexity of implementing a LDPC decoder, while maintaining accuracy. The new approximations approximate the standard sum-product algorithm (SPA), and can reduce the approximation error of min-sum algorithm (MSA) and have almost the same performance as sum-product algorithm (SPA) under both floating precision operation and fixed-point operation.       Recently Added Patents Mandolin slicer Medical probe Adaptor for attaching fifth wheel hitch Method and apparatus for vapor signature with heat differential Methods for PCO based UWB impulse radio with localized synchronization detection and retention Hearing device with automatic algorithm switching Container of a liquid filtration device   Randomly Featured Patents Low-complexity direct conversion receiver for delay-and-correlate transmitted reference signaling Method and a system for a multidimensional game Colored curable composition, color filter and solid-state imaging device Semiconductor device using polymer-containing photoresist, and process for manufacturing the same Method and apparatus for use in providing an identification token Sound absorbing apparatus for a supersonic jet propelling engine Underwater viewing device Pressure control valve Fluorine-containing organosilicon compound Tunable filter including a surface acoustic wave resonator and a variable capacitor © 2006-2008 PatentGenius.
