Design LDPC Codes without Cycles of Length 4 and 6
Design LDPC Codes Cycles of Length 4 and 6
2009/9/4
We present an approach for constructing LDPC codes without cycles of length 4 and 6. Firstly, we design 3 submatrices with different shifting functions given by the proposed schemes, then combine them...
Design of Short, High-Rate DVB-S2-Like Semi-Regular LDPC Codes
Short High-Rate DVB-S2-Like Semi-Regular LDPC Codes
2009/9/4
This work focuses on high-rate (R>4/5) moderate-length (1000≤n<5000) low-density parity-check codes. High-rate codes allow to maintain good quality of the preliminary decisions that are used in carrie...
Design of a VLSI Decoder for Partially Structured LDPC Codes
VLSI Decoder Partially Structured LDPC Codes
2009/9/2
The starting point of this work is the development of a new class of partially structured LDPC codes, very well suited for hardware implementation. Specifically these codes are built so that the edges...
