Assume communication company offers a free to air TV program which uses 8PSK for modulation. Assume further, the TV channel uses a channel from 500 MHz to 505 MHz and the selected symbol frequency (carrier frequency) is the lowest possible frequency for the TV channel. a. Calculate the symbol duration in seconds for each constellation when 4-periods of the carrier frequency are used for each symbol. b. What would be the best possible choice for the carrier frequency to minimize the interference. Justify your answer. c. Calculate the maximum baud rate when we use the lowest possible carrier frequency. d. Calculate the bit rate when we use the lowest possible carrier frequency.
