While Shannon's theorem confirms that in close to native conformations information is transmitted with limited error probability, additional random errors in sequence (amino acid substitutions) and in structure (structural defects) trigger a decrease in communication capacity toward a Shannon limit at 0.010 bits per amino acid symbol at which communication breaks down.
Denote the output signal of filter in each transmitting path by s(t), and the output of the m th (m = 1,..., N) transmitting channel with error by g m e j ϕ m.
Abbe's method is analogous to work by Claude Shannon, sometimes called the father of information theory, who showed that noise imposes a limit to the rate at which data can be transmitted with almost zero error.
We select A j ; j = 2,..., M such that if channel is in state j, transmitter can use Q j and ensures that the frames transmitted with this scheme have error probability less than FERth which is a target threshold for frame error rate (FER).
Assuming symbols 0, 1, 2, and 3 are transmitted with equal probability, the symbol error rate (SER) is calculated as P e = 1 4 p e 0 + 1 4 p e 1 + 1 4 p e 2 + 1 4 p e 3 (5).
The preamble is transmitted with collision but cannot be decoded by eNB due to wireless channel error.
This case was modeled by estimating the bit error ratio (BER) of the six received bursts per frame and assuming that the whole frame was transmitted with the profile which carries more information bits without suffering any bit error.
An MPEG-2 video bitstream is transmitted over an error-prone channel without error protection.
In the discussion above, it is assumed unrealistically that all messages are transmitted without error.
Shannon laid forth the idea that once information became digital, it could be transmitted without error.
On the other hand, hybrid coded video is very vulnerable to error propagation when transmitted over error prone channels.
