Hi All, is it possible to (example using a "for" or "do-while" cycle) automatic concatenate N-subcircuits
in SPICE using the netlist? I saw that in VHDL it's possible by using the command "generate". In Spice?
Thanks in advance for Your help. Best Regards,
Paolone
Look for VSAT networks. Under this category there are many and many examples You may find. However, now by now, like >>m_llaa<< say, one of the most important (at military and civil level) use is the GPS.
Your question is properly. In fact, Spread Spectrum techiques are born for Military use, due to the important features: 1) Narrow-Bandwidth Jamming Immunity, 2) Unrelevability (with the classical Scanners) and 3) Undecifrability (the carrier hope pseudocasually in frequeency).
The cost is an...
hitachi 3d acoustic super woofer driver circuit
Hi, I'm searching for the data sheet of circuit driver of the 3d Acoustic Super Woofer (ASW), mounted on the portable combo CD-Cassette, that were commercialized on the '90. Thanks, Paolone
What's Es/No mean?
If You works with a Channel Coding, for example convolutional coding with Rate R=k/n (where k is the number of informative simbols and n is the correspondent coded simbols), then You can write k * Eb = n * Es ==> Es = R * Eb: Es is the amount of energy needed to transimit...
Look @ Kay's "Introduction to statistical Signal Processing - Estimation Theory" and Porat's "Digital Processing of Random Signals: Theory and Methods".
list of books for digital communication
Digital Communications now cover a very large area of interest: Modulation, Channel Coding, Source Coding, Synchroniztion, Equalization, Diversity Techniques and a large number of specify applications (GPS, DVB-T/S, X-DSL, Optical Networks, ...). I think...
relation between snr and eb no
We must prior understand our respectively "language": if You define Eb how the amount of energy to transmit a binary symbol and No how the monolateral power spectrum density, then Eb/No is the SNR.
In general, the error probability depends by SNR, so You must...
You have just say all, but I want add an extra comment. ZF criteria (who can be apply if is satisfied the Lucky condition that say input peak distortion must be < 1) don't take care about channel noise, so if channel response go proximum to zero, cause the phenomena called noise enhacement...
spectrum esstimation book
I suggest to refer Kay's "Fundamentals of Statistical Signal Processing, Volume 1: Estimation Theory" () and Therrien's "Discrete Random Signals and Statistical Signal Processing"
