We investigate the potential of adaptive equalization techniques to mitigate inter-channel nonlinear interference noise (NLIN). We derive a lower bound on the mutual information of a system using adaptive equalization, showing that the channel estimation error determines the equalizer’s performance. We develop an adaptive equalization scheme which uses the statistics of the NLIN to obtain optim...

In this article, we present different space-time receive processing techniques for frequency selective multiple input multiple output (MIMO) channels and evaluate their performance. We present the solutions for linear zem-forcing (ZF) and Wenerfil ter (WF) equalization with latency time optimization and incorporate the Bell Laboratories Layered Space Time (BLAST) architecture to gain diversity....

This work explores aeronautical telemetry communication performance with the SOQPSKTG ARTM waveforms when frequency-selective multipath corrupts received information symbols. A multi-antenna equalization scheme is presented where each antenna’s unique multipath channel is equalized using a pilot-aided optimal linear minimum mean-square error filter. Following independent channel equalization, a...

This paper addresses the issue of advanced equalization methods for space-time communications over MIMO broadband wireless channel. Instead of resorting to conventional multiuser detection techniques (based on the straightforward analogy between antennas and users), we adopt a different point of view and separate time equalization from space equalization, thus introducing a higher degree of fre...

Loudspeaker equalization is an essential technique in audio system design. A well-known equalization scheme is based on the deconvolution of the desired equalized response with the measured impulse response of the loudspeaker. In this paper, a postprocessing scheme is combined with the deconvolution-based algorithm to provide a better equalization effect. Computer simulation results are given t...

Elimination of tank overfills is a significant problem for the petroleum industry. Since most tank receiving operations are manual, the operators rely heavily on tank level gauges and alarms for overfill prevention. Tracing the historical development of tank gauging and alarm systems provides insight into why independence is so important. This history is interwoven with interpretations, insight...

The novel ultrasonic NDT technique based on application of long range guided waves is proposed for detection of defects in a storage tank floor. The technique needs access only to the outer edge of the tank floor and do not require emptying and cleaning inside of the tank. The technique has been developed on the basis of the Lamb wave transmission tomography. The propagation of the guided waves...

this paper deals with an inspection of defects including corrosion and leakage by acoustic emission (ae) in an oil tank floor. in contrast to intrusive methods such as magnetic flux leakage, eddy current or ultrasonic, there is no need to emptying and entering the tank in ae method in order to inspection. in this research ae investigation and ae source location is presented in detail. the resul...
