A 220 mW 1 Gb/s 1024-bit rate-1/2 low density parity check code decoder
C. Howland, A. Blanksby · 2002
A 1024 bit rate-1/2 Low Density Parity Check (LDPC) code decoder has been implemented that matches the coding gain of equivalent turbo codes. The parallel decoder architecture supports throughputs up to 1 Gb/s and convergence in the decoding algorithm translates into extremely low switching activity with power dissipation under 220 mW.
