Adaptation Algorithm of Decision Feedback Equalizer with First Post-Cursor Cancellation for Backplane Serial Links
نویسندگان
چکیده
In multi-gigabit per second systems, due to speed limitation, decision feedback equalization with first post-cursor cancellation can cause additional pattern dependent jitters with conventional LMS adaptation algorithm. Combining LMS algorithm and edge equalization, effects of first tap feedback delay is relieved and more compromised timing and voltage margin is obtained. The result is verified through behavioral simulation.

An Information-Theoretic Derivation of the MMSE Decision-Feedback Equalizer
We consider the discrete-time Gaussian channel with inter-symbol interference (ISI). Under the assumption of perfect feedback, an information-theoretic derivation of the minimum mean-squared error (MMSE) decision-feedback equalizer (DFE) is presented. Whereas previous works have used information theory to analyze the zero-forcing and MMSE DFE structures, this work derives the MMSE DFE directly ...

A new compact line equalizer is proposed for backplane serial link applications. The equalizer has two control blocks. The feed-forward swing control block determines the optimal low frequency level and the feedback control block detects signal shapes and decides the high-frequency boosting level of the equalizer. Successful equalization is demonstrated over a 1.5m long PCB trace at 3.125-Gb/s ...

The speed of serial interface through a backplane channel suffers severe ISI (Inter Symbol Interference) caused by the limited bandwidth of the channel. In order to overcome the bandwidth limit, a pulse shaping circuit or an adaptive equalizer is used. This paper presents the comparison between two approaches. Prototype chip is designed for 10Gbps serial data communication through a 34-inch tra...

متن کاملA low complexity approach to Turbo Equalizer
The turbo equalizers (TEQ) proposed in literature utilize equalizers based on trellis, soft Wiener filters. The resulting complexity of these equalizers is exponential and cubic in terms of the sampled channel impulse response (CIR). The interference cancellation based decision feedback filter based equalizers requires adaptation of two filters simultaneously. In this paper, a low complexity eq...
