Question: Q12 Encoding (other than Spread Spectrum) In the figure below, the number of bits encoded per symbol (vertical axis) is shown against the signal-to-noise ratio

Q12 Encoding (other than Spread Spectrum) In the figure below, the number of bits encoded per symbol (vertical axis) is shown against the signal-to-noise ratio (horizontal axis) required for successful transmission. a) Does 16 QAM provide a significant advantage over any other encoding scheme on a noisy channel at 5dB SNR? Explain your answer. (2 marks) b) Does 16 QAM hold a significant advantage over 16 PSK on a 15 dB SNR channel? Explain your answer. (2 marks) c) What is the minimum SNR required for QPSK to work well? (2 marks) d) Would you say it can be advantageous to have an encoder which can encode any of the five schemes as well as a monitoring tool for the SNR ratio of the channel? What would you be able to do with such a setup? (2 marks)
