In this paper a novel hybrid algorithm for harmonics estimation in power systems is proposed. The estimation of the harmonic components is a nonlinear problem due to the nonlinearity of phase of sinusoids in distorted waveforms. Most researchers implemented nonlinear methods to extract the harmonic parameters. However, nonlinear methods for amplitude estimation increase time of convergence. Hen...

An interpolation-based unique decoding algorithm of Algebraic Geometry codes was recently introduced. The algorithm iteratively computes the sent message through a majority voting procedure using the Gröbner bases of interpolation modules. We now combine the main idea of the Guruswami-Sudan list decoding with the algorithm, and thus obtain a hybrid unique decoding algorithm of plane AG codes, s...

| This paper describes a new error resilient analysis{by{synthesis coding scheme and its application for robust still image transmission over DS-CDMA Rayleigh fading channels. The channel uses Reed-Solo-mon (RS) outer codes concatenated with Convolutional inner codes, and truncated type-I hybrid ARQ protocol based on the selective repeat strategy and the RS error detection capability.

We examine resource reservation schemes for the management of orthogonal variable spreading factor (OVSF) codes at the forward link of 3G mobile communications systems employing WCDMA. Like in every multiservice network, different rate calls in 3G systems will perceive dissimilar system performance if no measures are taken and the channelization code tree is treated as a common pool of resource...

By combining Modified quadratic congruence (MQC) codes with M-sequence codes, a hybrid MQC/M-matrices coding over spectral and spatial domains is proposed for spectral-amplitude coding optical code-division multiple-access network. The system performance evaluation shows better result than the one of the previous system using M-matrices coding scheme.

We consider an incremental redundancy (IR) type-II hybrid ARQ scheme based on multidimensional single parity check (SPC) product codes. Random interleaving is applied between dimensions, resulting in equivalent systematic, parallel or serially concatenated SPC codes. This enables larger interleavers and a larger range of overall code rates. The puncturing pattern used for IR transmissions of th...

Mobile communication systems have been adopting link adaptive transmission schemes such as adaptive modulation and coding (AMC) and hybrid-ARQ (HARQ). Several wireless mobile communication systems have considered highly efficient incremental redundancy (IR) hybrid ARQ scheme. However IR-HARQ with LDPC codes has not been specified yet. In this paper, we propose an IR-HARQ scheme with rate compat...
