Question

[20] ] Imagine you are designing a portable hand-held device that uses wireless communications. You have a license to operate the wireless modems over a 500 kHz portion of the radio spectrum. The engineers report that the average signal to noise ratio on this channel is 127:1. Equations below¹ a. What is the maximum possible data transmission rate that can be achieved? b. What signal to noise ratio (indicate units on your answer) is required to double the data rate? c. How many bits per symbol would be required to achieve the same data rate as part a in the absence of noise?
