The widely-used LMS algorithm for coefficient updates in adaptive (feedforward/decision-feedback) equalizers is found to be suboptimal for ASE-dominant systems but various coefficient-dithering app
LMS is suboptimal for ASE-dominant systems but various dithering approaches suffer from slow adaptation rate without guarantee of convergence.
An automatically adapted 43Gbit/s receiver comprising a 5-tap feed-forward and a novel 1-tap decision-feedback equaliser (FFE/DFE) has been applied to mitigate chromatic dispersion and PMD.
Coexistence with wireless-fidelity (Wi-Fi) is a key aspect for licensed assisted access (LAA) to succeed.
The authors propose to combine adaptive equalisation and differentially coherent reception. An appropriate LMS algorithm is deduced to adapt the equaliser.
Recently, considerable interest arose in finding ways to transmit and receive digital and analog data simultaneously over the 2-wire voiceband telephone channel.
The prevalence of nonlinearities and their distorting effect on highspeed data transmission over voiceband telephone channels has long been recognized.1 The effect of nonlinear distortion on linear
A common approach to data transmission is to code the amplitudes of successive pulses in a periodic pulse train with a discrete set of possible amplitude levels.
Carrier networks need to provide their customers with high availability of communication services.
In cellular OFDMA networks, there exists a fundamental trade-off between the achievable cell capacity and the degree of fairness among the users in the cell.
