COM-1509SOFT convolutional FEC codec, VHDL Source / IP core

Convolutional FEC codec, VHDL Source / IP Core

Bi-directional error correction encoder/decoder, including:

Convolutional encoding/Viterbi decoding
V.35 scrambling/descrambling
Serial HDLC framing/deframing

Convolutional codec with selectable rate and constraint lengths:

K = 5, rate 1/7
K = 7, rates 1/2, 2/3, 3/4, 5/6, 7/8
K = 9, rates 1/3, 1/2, 2/3

Maximum encoded output and coded input rates (Xilinx Spartan-6): 120 Mbps (for K=5, 7), 90 Mbps (K=9)
Differential decoder to resolve bit stream inversion
4-bit soft-quantized or 1-bit hard decision coded input
Built-in test tools:

PRBS-11 test sequence generation
BER measurement (coded, decoded)
