A reconfigurable dual-band low noise amplifier (LNA) for 3.4-3.6 GHz IMT-Advanced and 4.2-4.8 GHz UWB systems is presented in this paper. Two different input matching networks with source-inductive-degeneration cascode configuration are used to switch at two different frequency bands. The parallel capacitors between the input MOSFETs' gate and source are used to optimize noise factor of the LNA. The...
In many real-world communication systems, the channel noise is non-Gaussian due to the presence of impulsive noise as well as the background Gaussian noise. In such situations, the conventional Euclidean distance based decoder may suffer from the problem of severe metric mismatch. To overcome the problem, we recently proposed the joint erasure marking and Viterbi algorithm (JEVA) as a robust trellis...
