MATLAB indexing issue
because i copied some of this stuff from a decade old post, and evidently, Google Groups has changed the number of characters per line and we cannot control word wrapping in our posts in Google Groups, i have edited the line endings (and we'll let the lines wrap naturally). this should be much more readable t... 7 Jul 2010 13:27

pulsewidth and bandwidth
Hi Experts, I know bandwidth = 1/pulsewidth. After reconsider the pulse shape and ISI, this question comes to my mind.But how it comes in this way? Thanks, F ... 26 Jul 2010 22:40

soft decisions: what decision function to use?
When generating soft decisions from symbols, what's the best decision function to use? Is some linear approximation of a sigmoid suitable? What effect does the decision function have on the performance of the system? ... 7 Jul 2010 13:27

time delay in frequency domain?
I have a question on how to apply the Fourier transform time shift equality on a sinusoidal signal. A cosine signal after a 1/4 period delay is a sine signal. Consider the follow Fourier transform equality x(t) <-> X(f) x(t - a) <-> exp(-j*omega*a)*X(f) x(t) = cos(omega1*t) X(f) => {imp(omega + omega1) +... 6 Jul 2010 12:15

SI System urged to adopt
>Various news stories report the following: "In early 2010, Austin Sendek of UC Davis created a petition encouraging the SI system to designate "hella-" as the prefix for 10^27, following "yotta-" for 10^24." (Some sources mistakenly state that Sendek would like the nubmer 10^27 to be referred to as "a ... 6 Jul 2010 01:24
