On the Practical Aspects of Joint Passive Phase Conjugation and Equalization Underwater Communication Systems
Underwater acoustic communication systems suffer from the channel impairments which results in time spreading of the transmitted signal. In underwater environment, multiple replicas of the transmitted signal are received at the receiver through different paths, which causes significant Inter-Symbol Interference (ISI). Decision Feedback Equalizers (DFE) was utilized to overcome this type of inte...

Artificial neural network (ANN) has application in communication engineering in diverse areas such as channel equalization, channel modeling, error control code because of its capability of nonlinear processing, adaptability, and parallel processing. On the other hand, wavelet transform (WT) with both the time and the frequency resolution provides the exact representation of signal in both doma...
متن کاملBlind Equalization for MIMO FIR Channel in Wireless Communication Systems
In wireless communication systems, equalization process is needed to suppress the inter-symbol interference (ISI) caused by multipath channels. Conventional equalization techniques use training signals. Blind Methods are of great importance in the digital signal communication systems as they allow channel equalization at the receiver without the use fof training signals. A blind equalization in...

The second generation of digital video broadcasting (DVB-T2) standard utilizes orthogonal frequency division multiplexing (OFDM) system to reduce and to compensate the channel effects by utilizing its estimation. Since wireless channels are inherently sparse, it is possible to utilize sparse representation (SR) methods to estimate the channel. In addition to sparsity feature of the channel, the...
متن کاملMitigation of Intersymbol Interference with Equalization and Convolution Coding
In mobile radio communications, various phenomena such as multipath wave propagation, time dispersion, and fading introduce errors like Intersymbol interference (ISI), and other distortions into the signals that are transmitted over wireless channel in mobile radio communications. To combat errors, equalization (a sophisticated set of signal processing techniques), convolution coding and other ...
