In this paper, we study both the frame error rate (FER) and the block error rate (BLER) performance of spatially coupled low-density parity-check (SC-LDPC) codes. We consider protograph-based constructions of SC-LDPC codes under two different scenarios. In the case of terminated codes with block (flooding schedule) decoding, we examine how the FER scales with both the protograph lifting factor M and the termination length L. In the case of unterminated codes, in which a sliding window decoder continuously outputs blocks of target symbols in a streaming fashion, we examine the BLER associated with these blocks. We investigate the effect of protograph design on the streaming BLER by varying the lifting factor M and the coupling width w in such a way that the overall constraint length of the SC-LDPC code remains constant. We also investigate the BLER scaling behavior with M and w. Simulation results for both the binary erasure channel (BEC) and the additive white Gaussian noise channel (AWGNC) are included and performance comparisons are made to LDPC block codes (LDPC-BCs).
