Data errors from network device at high ambient temperature(60C)
I have a Raspberry Pi Compute Module 3 based network device that I am trying to get working at high ambient temperatures (up to 60C). When I run TCP packets through the device, I get checksum errors ...

Number of errors that can be detected with a single-bit even parity code word system?
How many errors can a transmission system which uses code words with 7 data bits and a single parity bit (Checking for Even parity) detect at the receiving end.
While I am aware of the fact that any ...

Decoding an unknown serial bitstream that does not fit 8-N-1
I am looking at an RS-485 signal using a scope and an analyzer (saleae). This is running a mystery bus (see below for more information). I would like to know how to fix my frame errors. I can't begin ...

In Proteus 8 simulation of the PIC16F84A assembly code (.asm), any setting (BSF) or clearing (BCF) of the pins <3:0> clears pin RA4!
After a thorough investigation, it turns out that the Proteus 8 simulation of the PIC16F84A (and possibly other MCU-s in PIC16 family) has a bug when interpreting the assembly language code, which ...

What effect does having 'measured' as a parameter in additive white gaussian noise?
I'm comparing the bit error rate of various modulation schemes with additive white gaussian noise in MATLAB.
There's the option to have this noise using 'measured' which measures the power of a ...

Need some help in bit error rate calculation for QPSK when using Gray coding
Why is Probability of Bit Error = 2 times the Probability of Symbol Error in QPSK with Gray Coding. Is it because one bit error has the potential to cause two symbol errors (2 symbols where they ...

Bitstream autocorrelation? - comparing two bitstreams - BER?
I am sending a PN9 sequence from a sender to a receiver and want to compare the received bitstream (RB) to the sent one (SB). I am assuming that the transmission will get distorted and want to somehow ...

how to understand the capacity in binary symetric channel (BSC)
According to the wiki about the BSC (binary symetric channel),
given the bit flip rate p,
the capacity is derived as :
H(p) = -p*log2(p) – (1-p)log2(1-p)
C = 1 - H(p).
the error probability p ...

Why bother with even parity?
I am using an SPI peripheral in my application. The peripheral returns packets containing 15 data bits, plus an Even Parity bit for error detection.
Therefore all zeros, and all ones both pass the ...

BER as a function of antenna's diameter
I hope that this community is the most suitable for this kind of question.
So I have to make a graph representing dependence of BER as a function of antenna's diameter (BER(D)) I know that antenna's ...

Neutron Single Event Upset (NSEU) how its effect is mitigated in electronics in space vehicles?
Since in the outer space the NSEU will be more common than in the earth, how the electronics in space vehicle is tacking the issue. I feel a solution will be existing for some decades but on google I ...
