Abstract
Orthogonal Frequency Division Multiplexing (OFDM) is one of recent years multicarrier
modulation used in order to combat the Inter Symbol Interference (ISI) introduced by frequency
selective mobile radio channel. The circular extension of the data symbol, commonly referred to as
cyclic prefix is one of the key elements in an OFDM transmission scheme. This paper study The
influence of the cyclic prefix duration on the BER performance of an OFDM-VCPL (Orthogonal
frequency division multiplexing - Variable Cyclic Prefix Length) system and the conventional
OFDM system with frame 64-QAM modulation is evaluated by means of computer simulation in a
multipath fading channel. The adaptation of CP is done with respect to the delay spread estimation
of the channel.
