This writeup examines the construction and performance of non-binary generalized low-density parity-check (GLDPC) codes. Recently, binary GLDPC coding techniques have been shown to improve upon conventional low-density parity-check (LDPC) codes by increasing the minimum codeword length, reducing error floors, and improving performance at lower coding rates. GLDPC codes replace the parity-check constraints...
Modern wireless communication systems employ a variety of methods to help ensure reliable data transmission in challenging environments. One method uses a channel code designed such that a given transmission can be decoded by the receiver as soon as a sufficient number of symbols is received. Such a scheme is referred to as rateless coding. Rateless codes are well known for their application to erasure...
