In section 3, the proposed normalized
adaptive equalization turbo receiver are described in detail.
In order to overcome these obstacles, we proposed an optimized
adaptive equalization system which is based on eye diagram tracking.
Considering the channel-to-channel differences of the multiple frequencies in the bandwidth,
adaptive equalization with a finite impulse response structure is employed in each of the channels to correct the channel transfer functions in [2].
The device supports Ethernet and OTN baud rates ranging from 24 - 28 Gbps and includes
adaptive equalization to support applications ranging from CEI-28G- VSR to CEI-28G-MR (up to 20dB insertion loss).
One of the best ways suggested for overcoming this effect is using
adaptive equalization methods in receivers.
Even more information results from IDL
Adaptive Equalization. Both these enhanced images, with white ridge impressions, were embedded in a larger 1900 x 1900 array prior to processing using 'IDLLevy.pro'.
Unlike 2.25 GHz receivers, the ADV7619 implements ADI's state-of-the-art
adaptive equalization technology with automatic adjustment to provide the best 3GHz receive performance across a wide spectrum of sources, cables and input signal speed.
Adaptive equalization is a mature technology in the field of data communication.
Now PCB designers have to contend with on-die termination, differential signaling and
adaptive equalization in order to get designs to work.
Additionally, enhanced receiver performance, with
adaptive equalization, allows restores of extremely noisy data without errors.
If the eye is totally closed at the receiver end, passive equalization cannot be used and
adaptive equalization (such as Decision Feedback Equalization) is the only choice available to designers to maximize the eye opening.
