In this letter, protograph-based folded spatially coupled (FSC) LDPC codes are proposed. The new folded-type structure is obtained by folding the spatial coupling chain of a conventional spatially coupled (SC) LDPC protograph and interlacing the nodes at staggered spatial positions. The proposed codes outperform the SC LDPC codes over single and multiple random-burst erasure channels. We extend the construction of the folded-type structure by connecting multiple one-sided SC LDPC chains for higher resilience to burst erasure channels. The FSC LDPC codes are also compatible with windowed decoder and outperform conventional SC LDPC codes.
