This paper presents pilot symbol aided channel estimation in Filter Bank Multicarrier (FBMC). FBMC has been employed widespread in communication applications because of its good spectral behaviors. Unlike Orthogonal Frequency Division Multiplexing, FBMC structure avoids imaginary interference. So that auxiliary symbols are employed and decrease peak to power ratio and improve achievable capacity....
In next generation communication systems high data rate, and higher transmission capacity through wireless channel are important for researchers. Filter bank based multicarrier (FBMC) modulation with offset quadrature amplitude modulation (OQAM) makes researchers interested due to its advantages over orthogonal frequency division multiplexing (OFDM). The paper indicates that OFDM, FBMC-QAM, multiple-input...
In this study, QMF (Quadrature Mirror Filter-quarter Mirror Filter) bank is proposed design hybrid windowing function based on Cosh and Hamming the use of the window. The performance of the filter banks are designed in different degrees; pass and stop band attenuation with failure to pre was evaluated taking into consideration. The obtained results of the intended QMF filter bank with Cosh-Hamming...
The past over the years, single or multi-dimensional signal processing applications, communication systems, biomedical signal processing, word coding, sub-band coding in applications such as efficient use filter banks; single filter instead of multiple custom filters come together with being designed. In this study, two-channel filter banks a special case known as the QMF (Quadrature Mirror Filter...
In this paper, a filter design approach which uses the harmony search algorithm for additive white Gaussian noise cancellation through an infinite impulse response digital filter, is described. In the digital filter design, a mitral valve Doppler signal and a 4th degree infinite impulse response digital filter were used. In order to improve the design, additive white Gaussian noise was added to the...
