On the Exact BER of Bit-Wise Demodulators for One-Dimensional Constellations [PDF]

open access: yes, 2012
The optimal bit-wise demodulator for M-ary pulse amplitude modulation (PAM) over the additive white Gaussian noise channel is analyzed in terms of uncoded bit-error rate (BER).

Temporal and Spatial Data Mining with Second-Order Hidden Models [PDF]

open access: yes, 2005
In the frame of designing a knowledge discovery system, we have developed stochastic models based on high-order hidden Markov models. These models are capable to map sequences of data into a Markov chain in which the transitions between the states depend
