Consider an OFDM implementation that uses 15 kHz subcarriers and use an OFDM symbol of 2048 subcarriers. The nominal cyclic prefix accounts for a 7% guard time. The extended cyclic prefix can use up to 25%. 1500 subcarriers can be used for data transmission. The rest are needed for pilot and null subcarriers. The transmission bandwidth is 20 MHz using 8 QAM modulation.
How many guard symbols does the nominal CP add?
How many guard symbols does the extended CP add?
What is the data rate for the nominal CP?
What is the data rate for the extended CP?
