From the rigorous review, it is concluded that a good equalization controller should have high equalization speed, high efficiency, small volume, simple wiring and execution, low cost and good extensibility.
In a broad sense, the obtained curves confirm what is mathematically demonstrated in Appendix, that an MMSE will provide a very high equalization weight when is exposed to a null, and that will do the opposite thing for a peak.
"I know there are times we've been low and others have been high, but equalization in New York is totally out of whack," he said.
A high-performance equalization scheme is described in this paper.
It is therefore an important challenge to develop high-performance equalization schemes for doubly selective channels.
On the contrary, the high performance equalization objective can be met if the prototype filter (employed in the FBMC/OQAM scheme) is designed using the frequency sampling technique introduced in [8] and developed in [5].
Thus, in order to be accepted, the FBMC/OQAM approach must have a high performance equalization capability, particularly in the asynchronous context, characterized by the fact that the system must compensate simultaneously the timing offset, the frequency offset, and the channel distortion.
Due to high-speed transmission and high-mobility terminals, equalization for time-varying and frequency-selective (a.k.a. doubly-selective) channels is an important issue.
This move indicates the extension of gender equalization of higher education opportunity from groups with a relatively higher parental educational level to those with a relatively lower level.
For high SNRs (25 dB in the considered case), CB-FMT with single-tap equalization provides higher achievable rate than OFDM for a Doppler below 400 Hz.
