Doubt regarding PDF 26 33 (10/14/2009 8:37:04 AM) comp.dsp Hi All I have some doubt regarding an equation in the following paper: http://www.lnt.e-technik.tu-muenchen.de/mitarbeiter/goertz/globecom03.pdf I believe in eqn. (3), the scaling factor should be 1/(2*pi*s... cpshah99

Convergence of Linear Equalizer 6 21 (9/15/2009 11:06:36 AM) comp.dsp Hi All In Haykin book of adaptive filter, he has explained tracking of LMS in non-stationary environment. In that he says that the tracking is problem specific i.e. tracking of system identification is differe... cpshah99

Ploting Impulse response 7 30 (9/7/2009 9:24:20 AM) comp.dsp Hi All May be this is trivial but I need some help. I am trying to plot impulse response of the channel. I have got a channel matrix of 71x1000 i.e. the row reprents 'time' and the column represents 'delay'.... cpshah99

Channel Estimation During Data period 19 28 (8/5/2009 10:42:13 AM) comp.dsp Hi All I am simulating time varying freq selective channel where the channel is changing for every symbol. The packet format is 511 training sequence followed by 2000 data symbols. Now at the receiver, as t... cpshah99

Convergence of adaptive DFE 3 20 (7/29/2009 12:58:54 PM) comp.dsp Hi All I am trying to demodulate real time data using adaptive DFE. The channel is highly time varying and the multipath spread is approx. 50 - 100 symbols at the data rate of 4ksps. I have 1000 symbols long... cpshah99

OT: How to write a good technical paper 35 30 (7/3/2009 6:48:08 PM) comp.dsp Hello All I guess for the first time I am asking something like this. I am facing troubles in order to write the work that I have done. The reviewers are not happy at all. The comments are very harsh. And I ... cpshah99

Normalizing Histogram 3 30 (6/25/2009 2:42:32 PM) comp.dsp Dear All I am trying to plot histogram of the o/p of equalizer. As the o/p is complex I will have to plot histogram of real and imaginary part separately. I know it is straight forward in matlab, but the probl... cpshah99

design of adptive DFE 32 36 (6/9/2009 3:59:52 PM) comp.dsp Hi All If you have to design a symbol spaced adaptive DFE using LMS or NLMS algorithm in real time, how will you select the number of feedforward taps, feedback taps and step sizes. But the conditions are: T... cpshah99
