Consider a binary communication channel transmitting coded words of n bits each. Assume that the probability of successful transmission of a single bit is p (and the probability of an error is q=1-p), and that the code is capable of correcting up to e (where e>= 0) errors. If we assume that the transmission of successive bits is independent, then what is the probability of successful word transmission? Hint: the word is successfully transmitted if there are e or fewer...

Prob.4 A digital transmission system sends strings of binary (0 or 1) bits through the channel to the receiver. Assume that the probability of a bit error in the channel is 10-2 and that a string of 1000 bits is transmitted (a) Calculate the probability that more than three bit errors will occur in the 1000 transmissions (b) Use the Poisson approximation to calculate the probability that more than three bit errors wil occur in the 1000 transmissions.

In a binary communication system with an asymmetric transmitter, bits 0 and 1 are generated with 0.4 and 0.6 probabilities respectively. The receiver receives the bit stream of data through a noisy channel with the noise mean of zero and variance of 0.2. If the bit amplitudes for 1 and 0 are respectively 0.75 and -0.75, what will be the BER.

A data packet is transmitted over a lossy wireless channel with
packet error rate 0.3. Most communication systems adopt
the Automatic Repeat reQuest (ARQ) protocol. That is, if a packet
is successfully (with probability 0.7) or unsuccessfully
(with probability 0.3) received, the receiver respectively
sends a one-bit ‘ACK’ or ‘NAK’ message (over a separate feedback
channel) to the transmitter. After receiving an ‘ACK’, the
transmitter will move on to the next packet transmission;
otherwise, the transmitter will re-transmit the same...

Let us consider the binary digital communication system in which bit 1 is represented by the waveform Acos(ωt) of bit duration T, where ω is the carrier radial frequency and A is the constant amplitude. On the hand, the bit 0 is represented by the following waveform instead (A/10)cos(ωt). During the transmission the channel has introduced the uniform random phase shift Φ and transmitted waveform is affected by zero-mean white Gaussian noise of variance σ2. To demodulate, we perform the...
