A Code Scheme for G3-PLC Physical Layer Specification Based on Turbo Code

In this paper, A G3-PLC coding scheme based on the Turbo code is proposed. The scheme replaces the convolution encoder in the G3-PLC standard with a Turbo encoder. The Turbo encoder based on random inner interleaver and odd-even punching is constructed to adapt to the G3-PLC standard. A comparison with the coding scheme in the G3 specification and LDPC code is performed, confirming that the proposed scheme has well trade-off in flexibility and reliability. Finally, an implementation on G3-PLC Data Concentrator is carried out to prove the Turbo scheme feasibility in future practical narrowband PLC system.
