Analytical expressions for the symbol error rate (SER) of MIMO systems are important from both design and analysis point of views. This paper derives exact and easy to evaluate analytical expression for the SER of an orthogonal space-time block coded (OSTBC) MIMO system with spatially correlated antennas, in which the channel signal propagation suffers from a degenerative effect known as a keyh...

Inter-symbol Interference (ISI) is well thought-out as a major problem in the wireless communication channel to transfer data. The purpose of the equalizer is to reconstruct the original signal by using filters or other techniques, and remove ISI. There are several methods to solve the problem. One of the methods is adaptive decision feedback equalizer based MSER (ADFEM) is Presented along with...

We investigate the sensitivity of Orthogonal Frequency Division Multiplexing (OFDM) waveforms to the joint distortion effects of various coexisting non-idealities in the implementation of transceiver radio frequency (RF) electronics, combined also with time variations of the multipath radio channel. We report closed-form performance analysis for a general OFDM mobile radio link, which includes ...

In an RGB-LED-based optical camera communication system, it is essential goal to have better performance in the data rate and BER. However, a higher symbol rate, due conventional sampling algorithm, deterioration of transmission brought by inter-symbol interference inter-channel significant. Innovatively, this paper, sub-image obtained captured frame received video encoded channel-attention-Net...

We present simple coding strategies, which are variants of the Schalkwijk-Kailath scheme, for communicating reliably over additive white noise channels in the presence of corrupted feedback. More specifically, we consider a framework comprising an additive white forward channel and a backward link which is used for feedback. We consider two types of corruption mechanisms in the backward link. T...

We investigate 128-level set-partitioning quadrature amplitude modulation (128-SP-QAM) experimentally and compare the performance to polarization-multiplexed 16QAM both at the same bit rate and at the same symbol rate. Using a recirculating loop we study both single channel and wavelength-division multiplexing (WDM) transmission and demonstrate a reach of up to 2680 km at a bit-error rate of 10...

An efficient and systematic LL(1) error recovery method is presented that has been implemented for an LL( 1) parser generator. Error messages which provide good diagnostic information are generated automatically. Error correction is done by discarding some input symbols and popping up some symbols from the parsing-stack in order to restore the parser to a valid configuration. Thus, symbol delet...

An analytical treatment of the performance of frequency hopped Gaussian frequency shift keying (GFSK) with differential detection in time-varying Rayleigh fading channels corrupted by additive white Gaussian noise (AWGN) is presented. Closed-form expressions for the bit error rate (BER) as a function of Eb/N0, modulation index, channel Doppler shift, and the timebandwidth product of the pre-mod...

This paper presents the convergence analysis of a prediction based blind equalizer for IIR channels. Predictor parameters are estimated by using the recursive least squares algorithm. It is shown that the prediction error converges almost surely (a.s.) toward a scalar multiple of the unknown input symbol sequence. It is also proved that the convergence rate of the parameter estimation error is ...
