How to window a time domain signal for 6 symbols with cyclic prefix length of 512 samples?

1. How do you find the cyclic prefix length?
2. What should be the length of the cyclic prefix in OFDM?
3. How many OFDM symbols are present in a slot with extended cyclic prefix?
4. What are the typical values of LTE cyclic prefix?

How do you find the cyclic prefix length?

Therefore, the number of samples allocated for cyclic prefix can be calculated as Ncp=Tcp*N/T, where N is the FFT/IFFT length, T is the IFFT/FFT period and Tcp is the duration of cyclic prefix.

What should be the length of the cyclic prefix in OFDM?

In LTE, the normal CP duration is 7% of the core OFDM symbol (i.e., samples and samples).

How many OFDM symbols are present in a slot with extended cyclic prefix?

There are seven OFDM symbols per slot for a normal cyclic prefix (six in the case of an extended cyclic prefix). In each of those seven OFDM symbols, a length-12 sequence, obtained by phase rotation of the cell-specific sequence as described earlier, is transmitted.

What are the typical values of LTE cyclic prefix?

LTE uses two types of CP, normal CP of 4.7 microseconds and Extended CP of 16.7 microseconds.
