Eliminating the OFDM cyclic prefix
A novel method is presented to estimate the frame time and carrier frequency offset in orthogonal frequency multiplexing (OFDM) systems [1] using a variable number of time-domain pilot signals. The performance and computational intensity of the proposed system is compared to a traditional OFDM system using redundant information from the cyclic prefix [2].
متن کاملCyclic Prefix Optimization of OFDM System
There are many methods to reduce the multipath effects in wireless communication. Multicarrier modulation for data transmission is one of the methods to overcome the effect of Inter Symbol Interference (ISI), also known as Orthogonal Frequency Division Multiplexing (OFDM). The analysis of Bit Error Rate (BER) performance suggests, OFDM is better than Code Division Multiple Access (CDMA) which i...
متن کاملCyclic Prefix Reduction Technique for OFDM System over Multipath Fading Channels
This paper presents a technique to reduce Cyclic Prefix (CP) length for Orthogonal Frequency Division Multiplexing (OFDM) in multipath fading channels. To reduce the CP length, a Time-domain Equalizer (TEQ), using long training OFDM symbols in the preambles, is used immediately after the channel. It can cancel the residual Inter Symbol Interference (ISI) and Inter Carrier Interference (ICI) cau...
متن کاملOn Synchronization in OFDM Systems Using the Cyclic Prefix
In this paper, we present a data-based method for simultaneous Maximum Likelihood (ML) symbol timing and carrier-frequency offset estimation in Orthogonal frequency-division multiplexing (OFDM) systems. The cyclic extension, a guardspace preceding OFDM frames, is of decisive importance for this method. It is shown that the redundancy introduced by this cyclic extension allows the estimation to ...
متن کاملThe Cyclic Prefix Length Influence on OFDM-Transmission BER
Orthogonal Frequency Division Multiplexing (OFDM) is one of the recent years equalization approaches used in order to combat the inter-symbol interference introduced by the frequency selectivity of the radio channels. The circular extension of the data symbol, commonly referred to as cyclic prefix is one of the key elements in an OFDM transmission scheme. The influence of the cyclic prefix dura...
