The proposed multi-resolution spectrum sensing (MRSS) technique is a flexible, low-power, high-speed spectrum-sensing solution for cognitive radio systems. Meanwhile, impairments of analog building blocks may degrade the accuracy of the proposed MRSS performance. In this paper, the effect of non-idealities of an integrator is explored. The dominant pole position is suggested to be less than 20% of...
In this paper, a reconfigurable CMOS equalizer is presented to accommodate vast variety of backplane channel loss characteristics. Backplane channels over different trace lengths and dielectric materials were measured and characterized. Feed-forward equalizer (FFE) topology with finite impulse response (FIR) architecture was chosen for optimal equalization for the corresponding backplane configurations...
Limitations in data transmission caused by band limitation in broadband communication links can be improved significantly by using equalization techniques. In this paper, a reconfigurable feed-forward equalizer employing a transition detector (TD)-based calibration technique that provides a universal channel compensation solution is presented. Moreover, the newly proposed TD-based calibration technique...
