Raptor code is the current standard of 4G long term evolution (LTE) evolved multimedia
broadcast and multi-cast services (eMBMS), which is viewed as a potential approach in the
design of ultra-reliable low latency communications (uRLLC) for 5G. This paper analyzes the
performance of finite length non-binary (over finite field of order q, GF (q)) Raptor codes
under ordered statistics decoder (OSD) towards uRLLC, where the non-binary Raptor code
ensembles by a non-binary low density parity-check (LDPC) code as pre-code and a non …

Raptor codes can approach the capacity of era-sure channel without accurate channel state
information at the transmitter side, which is viewed as a potential channel coding approach
to meet stringent requirements of ultra-reliable low latency communications (uRLLC)(block
error rate (BLER)≤ 10-5, and end-to-end latency≤ 1 ms). This letter investigates a modified
ordered statistics decoder (mOSD) algorithm for finite length non-binary Raptor code
towards uRLLC. The upper bound of BLER for the non-binary Raptor code under OSD is …
