Regarding the OFDM lab exercise, please refer to the OFDM setup slide in
https://ceiba.ntu.edu.tw/course/ec99ff/doc/week2/Ex1.ppt
Two different modulation cases should be implemented, QPSK and 16QAM. The
carrier number is 128 and the cyclic prefix is last 1/4 portion of the OFDM
modulated signal. The channel is AWGN this time (we can change the channel
model to multipath case in the future). Though the channel is AWGN and CP
does
not help improve the performance, I still hope you can implement the CP
insertion part so the program can be used later for multipath case.
By the way, attached please find a good reference about OFDM which contains
additional information about OFDM such as the history and the applications of
OFDM. Hope it can give you a better understanding about OFDM.
