Project: Data Packing QC-LDPC Decoder

1. (A) Nature order data packing into memory (B) The proposed order data packing

2. QC circularly shifts the data packing in the proposed data packing. The red arrow represents that after the cyclic shift of the data pack in line with the check node process.
   This illustration demonstrates the proposed data packing can avoid data conflict of random QC property

3. The proposed partial parallel architecture 6bit quantization

4. Finite state machine timesheet

5. 
   Testbench 1 of LDPC decoder 48bit input/ 408bit output:
   Input code data from file codeword.txt
   Test algorithm behavior for each single block
   Testbench 2 of LDPC decoder 48bit input/ 408bit output:
   Gaussian noise gen can run the desired block number
   Test the BER performance\
