Convergence of Linear Equalizer647 (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 response760 (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 period1952 (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 DFE338 (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 paper3549 (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 Histogram365 (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 DFE3262 (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
polar format algorithm664 (10/8/2009 11:26:58 AM) comp.soft-sys.matlab Hi, Has anyone got a sample code in matlab (or any other lang.) for "polar format algorithm" (range and azimuthal interpolation), for SAR applications ? Or could direct me to a paper which describes the alg... kamran4(59)
Noble price vs Nobel prize3269 (10/11/2009 8:40:49 AM) comp.dsp Hi all. Any others who were taken by surprise by this year's Nobel Peace Prize laureate? The debate has raged since the announcement of Obama's name, mainly over the question "what has he done to deserve it?"... allnor(8506)
Channel with Doppler spread1060 (10/12/2009 1:07:01 PM) comp.dsp I have a channel with a determinate Coherence Time. I want transmit information very very slow with a symbol time very very long, but then i have the problem that symbol time is longer than coherence time. How... nietorosdj(59)

WHO is WHO in COMP.DSP2545 (11/14/2009 9:31:05 PM) comp.dsp Gentlemen, I think it would be a good idea to put up a page with the brief information about the COMP.DSP participants. That would allow us to know each other better. Each entry could have a picture with few... nospam(2805)
Are DSP Processors losing out to ARM's?14864 (1/13/2010 7:01:25 AM) comp.dsp Is the DSP Processor landscape changing? Are they losing out to ARM Processors? Even companies like Ti (looks like) are focussing more on bringing out ARM microcontrollers and processors. How do DSP experts p... bharat310(237)
LDPC code10401 (2/15/2010 9:07:07 PM) comp.dsp
Recently I simulated a regular rate 1/2 LDPC code over AGWN and I got the
expected BER plot.
Then I thought to simulate the same code over frequency selective channel.
I am using linea... cpshah99
