In this paper, the authors propose the interleaving gain in two different distributed turbo-coding schemes: Distributed Turbo Codes (DTCs) and Distributed Multiple Turbo Codes (DMTC) for half-duplex relay system as an extension of their previous work on turbo coding interleaves design for direct communication channel. For these schemes with half-duplex constraint, the source node transmits its information with the parity bit sequence(s) to both the relay and the destination nodes during the first phase. The relay received the data from the source and process it by using decode and forward protocol. For the second transmission period, the decoded systematic data at relay is interleaved and re-encoded by a Recursive Systematic Convolutional (RSC) encoder and forwarded to the destination.
