Hi everyone , Does anyone can help me on my project?
i need matlab simulations of ? A Blind Algorithm for Estimating **pseudo**-**noise** **sequence** of DSSS Signal in Lower SNR Conditions ? . If anyone have it sent me : rezadigit@yahoo.com. It as i need to submit my results very soon and these codes would help me finish my report in time

Is it the same as the white **noise** which means the power is equally divided in the whole frequency range?
If so, how does it come? Any reference is preferred.
Now I've built a **pseudo**-random **sequence** using linear feedback shift register(LFSR), and I'd like to check its power spectral, is it possible to make it out using Cadence and how? (...)

A **pseudo**-random **noise** (PN) **sequence** is a **sequence** of binary numbers, e.g. ?1, which appears to be random; but is in fact perfectly deterministic. The **sequence** appears to be random in the sense that the binary values and groups or runs of the same binary value occur in the **sequence** in the (...)

I've seen zener diodes and reverse polarised BE junctions folowed by amplifiers used as **noise** sources in some simple test equipment (home made).
For better performance use a **pseudo**-random binary **sequence** (PRBS) generator connected to a DAC.
Look in The art of electronics - Horowitz, a chapter is about PRBS generators using feedback shif

Hi,
Yes the number **sequence**s are generated by an algorithm of sorts. Hoever the **sequence** is usually generated by a **pseudo** **noise** **sequence** (thus random) and then filtered to assure correctness.
To ensure that the codes are not faked a database of valid codes are kept. Once the pin code is recieved by the (...)

I guess you CAN'T! All that you can do with logic gives you more or less **pseudo**-RANDOM **sequence**s.
True random **sequence** can be generated using the help of **noise** generator. There is an application note on the web (can't recall the magazine nor the name of the article right now, sorry) that uses Zener diode as broadband (...)

in addition to the stuff from bartart:
xapp052 (especially this one), xapp217, xapp220 from Xilinx documentation.
These are LFSR (Linear Feedback Shift Register) designs that produce **pseudo** (careful!)-random **sequence**s. This means that eventually they get repeated. But if you have e.g. a 32-bit LFSR producing a maximal length **sequence**, (...)
