Abstract :
In this paper, an application layer hybrid error correction scheme with Reed-Solomon (HEC-RS) code is proposed to satisfy the very low packet loss ratio (PLR) requirement under a strict latency limit for DVB services over wireless LANs. The PLR performance of the HEC-RS scheme is analyzed and compared with the HEC scheme based on the packet repetition (HEC-PR) technique and an adaptive forward error correction (AFEC) scheme based on RS codes. It is found that the needed redundancy information (RI) of the HEC-RS scheme is much less than that of the AFEC scheme. However, if the group size and link PLR are small enough, the needed RI of the HEC-RS scheme is proven to be much more than that of the HEC-PR scheme. As a result, the optimum performance can be achieved when combining the HEC-PR and the HEC-RS scheme.
