Are errors in the optimal syndrome decoding of Hamming codes correlated?
I was reading Mackay's Information Theory, Inference and Learning Algorithms and in the example of transmitting an image using $(7, 4)$ Hamming codes over a binary symmetric channel, the text mentions ...

Error correction technique for 4 kB of data with 10-15% bit errors in an embedded microcontroller?
I'm working with an embedded project that uses a 4 kB buffer. Every once in a while something happens which introduces 10-15% bit errors, scattered throughout the buffer. Can someone please recommend ...

Error probability of BPSK with intersymbol interference
Consider an AWGN channel with BPSK modulation. Assume that
the information bits are i.i.d. Bernoulli with parameter 0<p<1,
we have ISI due to a timing offset at the transmitter, and
the decoder ...

Data rate for an ASK modulation [closed]
A telephone line with a bandwidth of 3 kHz and an SNR of 6 dB. I am asked to calculate the maximum bitrate on this line and the error probability, knowing that ASK modulation is used.
For ASK ...

SECDED in the presence of more than two errors
Is there a way to calculate the number of errors that will be caught (or missed) by SECDED when there are more than two errors? I'm thinking of an issue such as a badly-timed data strobe, where the ...

Do ASCII or Unicode Bit-Level Anagrams exist? [closed]
Is there such a thing as a bit-level ASCII anagram, that forms a natural language word when the bits are interpreted as ASCII from left to right, but a different natural language word when interpreted ...

Effect on sampling time on BER
Just for some background context:
A digital signal has jitter present on it. In this situation there is
only random jitter (RJ), which is unbounded and normally distributed.
When the digital signal ...

CAN: End-Of-Frame for detecting stuffing errors?
The end-of-frame consists of 7 recessive bits. It is often written that it is used to detect stuffing errors by a receiver. I also read that if the 7th bit is driven to dominant level, the transmitter ...

Why does NOR flash have 0% bad blocks?
Why does NOR flash memory have 0% bad blocks and ECC is not mandatory?
From my understanding, NOR flash and NAND flash are made of similar flash cells (they are only "externally" wired in ...

Is a bit error rate close to 1 just as desirable as one that is close to 0?
Let me explain the premise. If you have a communication system, and you know with a very good confidence margin what the bit error rate is, would you be able to exploit the properties of high bit ...

How does DPSK work? What are the advantages compared to BPSK?
I have two questions that I would appreciate some help with.
Comparing BPSK and DPSK I noticed that BPSK has lower BER. Why is this?
Are there other advantages of using one over the other?
In what ...

How does radiation produce transient bit errors in DRAM?
Ionizing radiation can produce transient bit errors in volatile RAM. What is the exact mechanism by which this occurs?
E.g., is there a threshold energy level for a single photon or neutron to ...

Does Carrier frequency offset (CFO) means difference of the message frequency and integrator?
Can anyone here tell me what is CFO? Initially, I thought it might be when the message signal mi, that is
$$r(t) = 2P cos(2\pi fc*fi+\delta f)$$ doesn't match with integrator $$\int_0^T r(t) * cos((...
