Projective parameterized linear codes
In this paper we estimate the main parameters of some evaluation codes which are known as projective parameterized codes. We find the length of these codes and we give a formula for the dimension in terms of the Hilbert function associated to two ideals,

Partial IDS decoding based on the base graph of protograph LDPC codes
The residual belief propagation (RBP) algorithm, which is the most classic informed dynamic scheduling strategy, achieves outstanding performance in error correction and can drastically accelerate convergence speed.

On the Trifference Problem for Linear Codes
We prove that perfect $3$-hash linear codes in $\mathbb{F}_{3}^{n}$ must have dimension at most $ \left(\frac{1}{4}-ε\right)n$ for some absolute constant $ε> 0$.

On Linear Complementary Pairs of Codes [PDF]
We study linear complementary pairs (LCP) of codes $(C, D)$ , where both codes belong to the same algebraic code family. We especially investigate constacyclic and quasi-cyclic LCP of codes. We obtain characterizations for LCP of constacyclic codes and LCP of quasi-cyclic codes.

QPSK Block-Modulation Codes for Unequal Error Protection [PDF]
Unequal error protection (UEP) codes find applications in broadcast channels, as well as in other digital communication systems, where messages have different degrees of importance.

Line codes are widely used to protect against errors in data transmission and storage systems, to ensure the stability of various cryptographic algorithms and protocols, to protect hidden information from errors in a stegocontainer. One of the classes of

On Block-Coded Modulation Using Unequal Error Protection Codes Over Rayleigh-Fading Channels [PDF]
This paper considers block-coded 8-phase-shift-keying (PSK) modulations for the unequal error protection (UEP) of information transmitted over Rayleigh-fading channels.

Several new and interesting properties of 'linear intersecting codes' are studied. The cyclic structure as well as the duals of such codes are also discussed. Relationships of such codes with many well-known codes in the binary and non-binary cases are established. Almost every study made in the paper is illustrated with an interesting example.

Low Complexity Encoding for Network Codes [PDF]
In this paper we consider the per-node run-time complexity of network multicast codes. We show that the randomized algebraic network code design algorithms described extensively in the literature result in codes that on average require a number of ...

Quasi-linear network coding [PDF]
We present a heuristic for designing vector non-linear network codes for non-multicast networks, which we call quasi-linear network codes. The method presented has two phases: finding an approximate linear network code over the reals, and then quantizing it to a vector non-linear network code using a fixed-point representation.
