‎Let p be an odd prime‎. ‎The main purpose of this paper is to establish and exploit the algebraic structure of some repeated-root two dimensional constacyclic codes of length 2p^s.2^k over the finite field F_{p^m}‎. ‎Moreover‎, ‎we study all self...

In this paper, we investigate the structure and properties of cyclic codes over the rings F2 + uF2

with u2 = u and F2 + uF2 + u2F2 with u3 = u. We find a set of generators for these codes. Examples

of cyclic codes of various lengths...

Two-dimensional cyclic code is one of the natural general-izations of cyclic code. In this paper we study the algebraic structure of some two-dimensional cyclic codes and their dual codes....

A Relay network with two relays is considered.A new achievable rate is obtained using a new network coding which includes the previous rates....

An N-receiver quantum dense coding scheme, in the case of high-dimensional Hilbert spaces, are investigated in this paper. A sender can send his messages to many receivers simultaneously....

One of the most important open questions in the

theory of quantum convolutional coding is to determine a

minimal-memory, non-catastrophic, polynomial-depth convolutional

encoder for an arbitrary quantum convolutional code...

power degradation rates into consideration, this

algorithm assigns higher priority to the users who have

higher speeds. A priority based AMC (Adaptive

Modulation and Coding) is also performed for better

performance. The analysis results...
