| Abstract: |
| Low density parity check(LDPC) code based on finite geometry has practical value.This paper introduces the principle and basic construction method,discusses the concept of euclid finite geometry,proposes the construction of euclid finite geometry LDPC codes,and also provides improvement method of EG codes. |
| Key words: LDPC codes,euclid geometry,parity-check matrix,cyclic-shift |
