Small-sized packet error rate reduction using coded parity packet approach

摘要

A two-stage coding scheme incorporated with a square M-quadrature amplitude modulation (QAM) scheme is proposed to realize multiple non-discrete data rates while reducing the packet error rate (PER) at small packet sizes. Subject to the intended code rate, Turbo-coded parity packets are generated through bit-wise XOR combinations of the source packets to provide additional soft information which can be produced, combined and shared by the Turbo decoder for each received packet to reduce the PERs.
