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...

Suppose a binary message is transmitted through a noisy channel. The transmitted signal S is equally likely to be 1 or-1, the noise N follows a normal distribution N(0,4), and the received signal is R-S + N. The receiver concludes that the signal is 1 when R > 0 and-1 when R<0. What is the error probability when one signal is transmitted? ·What is the error probability when one signal is transmitted if we triple the amplitude of the transmitted...
