7. IEEE 802.11a uses ODFM with 52 data carrying subcarriers, 4 pilot subcarriers, 8 guard subcarriers with a subcarrier spacing of 312.5kHz. 4 pts each a. What is the symbol time in us? b. What is the approximate RF bandwidth in MHz? c. What is the length of the IFFT/FFT used in IEEE 802.11a transmitters and receivers. d. The highest order modulation used in IEEE 802.11a is 64-QAM, what is the highest bit rate in Mb/s. e. The maximum specified rate for IEEE 802.11a is 54Mb/s, if the result from part d. is larger than 54Mb/s indicate possible sources of the difference. f. What is the purpose of the CP in OFDM?
