A- A communication channel transmits binary digits, i. e. O's and l's. The probability of error in transmission of either digit is 0.2. To reduce the chance of error, we transmit n bits for each digit as follows: a super-symbol 00....0 is transmitted instead of 0 or super symbol 1111....1 is transmitted instead of 1. a) What is the probability of error using the super-symbol strategy with 5 assuming that we receive the correct result if 3 or more of...
4- A binary communication channel introduces a bit error in a transmission with 10 pts probability 0.01. Let X be the number of errors in 10 independent transmissions. (a) Find the pmf of X if X takes on value in the set Sx-(1,2,3,4,53. (b) Find the mean, the mean square, and the variance of X. 10 t.
In wireless communication system, the amplitude of the communication channel response in volts (V) is often modeled by Rayleigh random variable Xwith density x-a 0, x< a. For this problem, assume a 0 and b-2. (a) Find the probability that the amplitude is less than 1V. (b) Find the probability that the amplitude of channel response is greater than 5V.
(2) In binary communication system, we send "0s and ""s and due to noise and channel distortion receiver sometimes makes errors with probability p. We also send these information bits in the form of packets (e.g., group of 10 bits) i) What is the probability of having a packet error that carries 100 bits of information? İİ) What is the probability of having at least 2 bit errors in a 100-bit packet? (2) In binary communication system, we send "0s...
7. The input U of binary communication channel is either -2.5 or +2.5 representing bit values b = 0 and b = 1 respectively, where P(b = 1) = 0.75. The channel output is given by V = U+N where “channel noise” N is a continuous random variable whose pdf is a symmetric triangular function in the range (-3, +3). Assume that U and N are independent. The receiver decodes the channel output to produces a bit value b as...

3. (20 points) Two communication devices are using a single-bit even parity check for error detection. The transmitter sends the byte 10101010 and, because of channel noise, the receiver gets the byte 10111011. Will the receiver detect the error? Why or why not?
A binary communication channel transmits coded words of 5 bits, and each bit in the word is independent of the others. The probability an individual bit has an error is 0.03. You are interested in modeling the number of bits in each 5-bit word that has an error. Name the distribution appropriate to model this scenario. Use the proper notation, and include the value(s) of the distribution parameter(s). Enter you response in the textbox below What is the expected number...
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...
