I started working on FEC for burst FSK system over multipath channel. I
want to ask the community here about what type of FEC would be best for
such system. Which type of FEC is being used...

The primary advantage of digital transmission over analog transmission is
Noise Immunity. A digital signal (in comparison to an analog signal) is
inherently more immune to noise. Why the word "inheren...

I have a 4x3 job shop scheduling problem that I need to find it's optimal
solution using matlab codes. I have the codes ready but need to modify
them a little bit.
first code is swarm, alrea...
I just ran across an interesting article, by
Alan Oppenheim, regarding the early history of
DSP. If you have nothin' better to do, you
might enjoy having a look at that ...

I came across the following formula to calculate pitch from accelerometer
pitch = atan2(Ay, sqrt(Ax^2+Az^2))
Is this correct?
Now a slightly complicated st...

I came across this online :
"2.1.4 What is the delay of a linear-phase FIR?
The formula is simple: given a FIR filter which has N taps, the delay is:
(N - 1) / (2 * Fs), where Fs is the sampling f...
In Julius' 5/18/15 reply to my post (Subject: An
