CP Length specifies the cyclic prefix mode for non-MBSFN subframes and the non-MBSFN region of MBSFN subframes. The length of the cyclix prefix can be autodetected or can be specified as Normal ( CP 1) Contention period, or 2) Cyclic prefix length = 7.03125% the length of the symbol), or as Extended (CP Length = 25% the length of the symbol).

Nevertheless, the overhead of CP leads to drawback for high transmission efficiency in varying mutipath channels. To address this issue, a novel SC-FDE transmission scheme with length-adaptive CP is Cyclic prefix provides a guard period in front of each OFDM symbol to guard against multi-path delay spread introduced by the channel, while Raised Cosine Filter is used in OFDM for pulse-shaping or smoothing the discontinuities between adjacent OFDM symbols or to reduce out-of-channel emissions in the frequency domain view. Orthogonal frequency division multiplexing (OFDM) is a modulation technique that resists the effects of a multipath channel when provided an ample cyclic prefix. No intersymbol interference is caused in channels whose impulse responses are shorter than the cyclic prefix length. However interference arises when this is not the case. This paper describes the degradation of the system under this In order for the cyclic prefix to be effective (i.e.

8, 16and 32 cyclic prefix subcarriers are added respectively. Cyclic prefix duration is determined by the expected duration of the multipath channel in the

The reduced Guard Interval in Coherent-OFDM systems accomplished less ICI because shorter symbol intervals are employed [10, 11], if the cyclic prefix length is high, this takes higher vitality This video explains the Cyclic Prefix in OFDM and DMT from a signals perspective.
