This paper proposes a distributed joint source-channel coding (DJSCC) scheme using polar-like codes. In the proposed scheme, each distributed source encodes source message with a quasi-uniform systematic polar code (QSPC) or a punctured QSPC, and only tra... see more

The generator matrices of polar codes and Reed–Muller codes are submatrices of the Kronecker product of a lower-triangular binary square matrix. For polar codes, the submatrix is generated by selecting rows according to their Bhattacharyya parameter, whic... see more

In this paper, we propose a rate-compatible (RC) parallel concatenated punctured polar (PCPP) codes for incremental redundancy hybrid automatic repeat request (IR-HARQ) transmission schemes, which can transmit multiple data blocks over a time-varying chan... see more

Polar codes are the first family of error correcting codes that provably achieve the capacity of symmetric binary-input discrete memoryless channels with low complexity. Since the development of polar codes, there have been many studies to improve their f... see more

In this paper non-trivial non-linear binary systematic AMDS codes are classified in terms of their  weight distributions, employing only elementary techniques. In  particular, we show that their length and minimum distance completely determine&n... see more

Turbo codes are the error-coding schemes applied nowadays in wireless networks. In navalapplications, the information is mostly sent through wireless networks and the data is moreprone to noise. Since very important data has to be communicated, it is nece... see more

In this paper a Non Uniform shaped patch antenna has been designed, simulated and optimized. Microstrip patch antennas with linear based on general requirement network have been investigated. All of the singles and arrays patch antennas are implemented in... see more

La ecuación de dispersión de ondas circularmente polarizadas se ha encontrado para plasmas con polvo y dos especies de granos. Se asume que las ondas se propagan en un campo magnético uniforme. Se asume el plasma distribuido uniformemente cuando no hay pe... see more

Scanning polarimeters, which utilize multi-angle, multispectral polarimetric observations from aircraft and orbit, represent the next generation of instruments capable of determining aerosol and cloud properties remotely. Retrieval of these properties fro... see more
