Understanding Cyclic Prefix in LTE by Sunil Samadhiya is a document available to read on EtoBox.
The cyclic prefix (CP) is used in LTE and other technologies to eliminate intersymbol interference. It works by copying and repeating a portion of each transmitted symbol and appending it to the end, acting as a guard interval. This allows the receiver to correctly identify symbol boundaries and correlate signal information despite multipath effects. Different sized CPs are defined for different propagation environments, with a normal CP of 4.7 microseconds for shorter distances and an extended CP of 16.67
