ANSWER:
A binary transmission system sends a 0 bit by transmitting a zero volts signal, and a 1 7 A binary bit bytransmitting +2 volts signal. The received signal is corrupted by noise and is givern by: Y-X+N, where X is the transmitted signal, and N is a noise voltage with double- exponential pdf given by; 0 1เ The receiver detects the transmitted signal by comparing Y to a threshold voltàge of +1 volts. If Y<+1 then the rcceiver decides that U is transmitted. Otherwise if Y20 the receiver decides that “I ” is transmitted. Find the df of Y given that transmitter sends 0 bit, and find pdf of Y given that Transmitter sends 1bit. 3 pt. 3 pt c. Find the probability of error for this receiver, which is the probability that the receiver 4 pt b. Assume that 0s and Is are sent with cquai probability find pdfotY. detects I given that the transmitter sends IOR the receiver detects 1 given that transmitter sends 0.

Problem 6: Nonlinear Channel Suppose a transmitter sends a signal X over a channel, where X is exponentially distributed with mean 1. The channel non-linearly distorts the transmitted signal, such that the signal at the receiver is given by Y-1-e-Ax, where λ > 0 is a constant. The receiver then estimates X using a linear estimator X based on Y which minimizes the mean squared error between X and X. Find this linear estimator

In a communication system, bits 0 and 1 are planned to be transmitted. The probability of transmitting the bit Ois 0.84. During the transmission, each bit is flipped (.e., turning the bit 1 into the bit or the bit into the bit 1) with probability 0.14. Random variables X and Y are defined to denote the transmitted and received bits, respectively. Calculate the correlation coefficient between X and Y. Answer: CHECK
