“…This deficiency is addressed in [16]- [18] by applying post-decoding processing on the frames which decoding fails. However, these schemes incur a high complexity overhead [16] and/or impose certain assumptions on the bit-error-rate in the unsuccessfully-decoded frames, thus, limiting their applicability [17], [18].…”

A novel inter-frame coding approach to the problem of varying channel-state conditions in broadcast wireless communication is developed in this paper; this problem causes the appropriate code-rate to vary across different transmitted frames and different receivers as well. The main aspect of the proposed approach is that it incorporates an iterative rate-matching process into the decoding of the received set of frames, such that: throughout inter-frame decoding, the code-rate of each frame is progressively lowered to or below the appropriate value, prior to applying or re-applying conventional physical-layer channel decoding on it. This iterative rate-matching process is asymptotically analyzed in this paper. It is shown to be optimal, in the sense defined in the paper. Consequently, the data-rates achievable by the proposed scheme are derived. Overall, it is concluded that, compared to the existing solutions, inter-frame coding presents a better complexity versus data-rate tradeoff. In terms of complexity, the overhead of inter-frame decoding includes operations that are similar in type and scheduling to those employed in the relativelysimple iterative erasure decoding. In terms of data-rates, compared to the state-of-the-art two-stage scheme involving both error-correcting and erasure coding, inter-frame coding increases the data-rate by a factor that reaches up to 1.55×.H. Zeineddine and M. M. Mansour are with theand (1−x J ) dc < 1−x otherwise. In addition, X c converges to e −(1−µ) as J → ∞.From Lemma 4, it can be concluded that for an arbitrarily small γ, ∃J such that: X c < e −(1−µ)+γ ∀J > J .Therefore:(1 − x J ) dc < 1 − x ∀x > e −(1−µ)+γ and J > J .

In this paper the performance of LT codes is analyzed. And then, for the remaining part of information which can be decoded still exists when decoding failure, an improved message passing decoding algorithm which retains the original algorithm framework is proposed. The simulation results have shown that the improved message passing decoding algorithm improves the decoding rate and reduces decoding overhead on the premise of appropriately increasing decoding complexity.
