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 long should the cyclic prefix be?
The length of the cyclic prefix should be at least equal to the number of channel taps minus one, so that the linear channel filtering appears as if it is a cyclic convolution.
What is a cyclic prefix required in an OFDM?
The cyclic prefix allows a OFDM transmitter receiver pair to accomplish to important objectives, provided that the length of the multipath channel is less than or equal to the length of the cyclic prefix plus one: 1) it eliminates interblock interference, and 2) it enables easy equalization, as for the remainder of the ...
What is normal cyclic prefix?
Δf, step between subcarriers; l, number of the symbol in the time slot. The normal cyclic prefix is used in case the delay between the different reflected signals is low, which is the case in cells of small diameter (microcell, pico-cell, femto-cell).
