“…For the case of message-wise UEP, our AE-based codes significantly outperform the construction considered in [5] based on the union of coset codes. For bit-wise UEP, the proposed AEbased codes outperform UEP rateless spinal codes [9] and UEP codes based on the superposition of random Gaussian codes [10]. Moreover, for the proposed AE-based codes, a simple and flexible procedure of fine-tuning the weight parameters provides a desired trade-off among error probabilities of different importance classes.…”

We present a novel autoencoder-based approach for designing codes that provide unequal error protection (UEP) capabilities. The proposed design is based on a generalization of an autoencoder loss function that accommodates both message-wise and bit-wise UEP scenarios. In both scenarios, the generalized loss function can be adjusted using an associated weight vector to trade off error probabilities corresponding to different importance classes. For message-wise UEP, we compare the proposed autoencoder-based UEP codes with a union of random coset codes. For bit-wise UEP, the proposed codes are compared with UEP rateless spinal codes and the superposition of random Gaussian codes. In all cases, the autoencoder-based codes show superior performance while providing design simplicity and flexibility in trading off error protection among different importance classes.

“…Practical designs of bit-wise UEP codes are more frequent in the literature, due to their applicability in, e.g., improved packet header protection or multimedia communication protocols. For example, bit-wise UEP has been proposed for coding schemes such as LDPC [7], fountain [8], or spinal codes [9].…”

“…In bit-wise UEP, a message is encoded into a sequence of bits and different subblocks of bits represent different importance classes that are protected differently [6]. Practical applications of bit-wise UEP codes, such as improved header protection or scalable multimedia communications, led to bit-wise UEP designs of popular coding schemes such as LDPC [7], fountain [8], or spinal codes [9]. Message-wise UEP codes have been investigated in applications such as alert message transmission and in certain joint source-channel coding scenarios [5].…”

We present a novel autoencoder-based approach for designing codes that provide unequal error protection (UEP) capabilities. The proposed approach, based on a generalization of an autoencoder loss function, provides a versatile framework for the design of message-wise and bit-wise UEP codes. Using an associated weight vector, the generalized loss function can be used to trade off error probabilities corresponding to different importance classes and to explore the region of achievable error probabilities. For message-wise UEP, we compare the proposed autoencoder-based UEP codes with a union of random coset codes. For bit-wise UEP, the proposed codes are compared with UEP rateless spinal codes and the superposition of random Gaussian codes. In all cases, the autoencoder-based codes show superior performance while providing design simplicity and flexibility in trading off error protection among different importance classes.

“…In [15], information symbols are protected unequally using fountain codes, whereas in [16] an efficient scheme is proposed to construct fountain codes with UEP property. In [17], a UEP scheme based on rateless spinal code is proposed. In [18], a rateless coding based UEP scheme is investigated by concatenating the systematic polar code (SPC) and spinal code.…”

Cross-layer unequal error protection using 64-HQAM and RCPT codes for robust image communication

In unequal error protection (UEP) schemes, the bits are protected according to their significance in terms of distortion reduction capability during the reconstruction process. The conventional UEP schemes are primarily designed either using forward error correction at application layer of network architecture, or hierarchical modulation at the physical layer. In this paper, an optimized cross-layer UEP scheme for set partitioning in hierarchical trees coded images is investigated. The proposed scheme uses rate compatible punctured turbo codes at application layer and two-layered 64-hierarchical QAM (64-HQAM) at physical layer. Simulation results show that proposed cross-layer UEP performs slightly better than application layer’s optimized turbo coding for additive white Gaussian noise channel but performs significantly better in flat Rayleigh fading channel, specifically under poor channel conditions. The proposed scheme is highly bandwidth efficient having the robustness performance close to that of the scheme using hierarchical 4-PAM (H 4-PAM). Complexity analysis of the proposed solution has been carried out.
