چکیده
In this paper, we show an implementation of orthogonal frequency-division multiplexing (OFDM) systems including advanced Two-Dimensional (2D) interpolation-based channel estimation. The presented channel estimation technique improves the performance of OFDM system in terms of bit error rate (BER). The technique is based on planar equations to find accurate channel information of carriers in the edge of the user burst area. We have implemented proposed channel estimation technique using Digital Signal Processor (DSP), TMS320C6416T. The performance of proposed system is verified through Matlab® simulations in various signal environments and is compared with the performance of system including conventional channel estimation.

The second generation of digital video broadcasting (DVB-T2) standard utilizes orthogonal frequency division multiplexing (OFDM) system to reduce and to compensate the channel effects by utilizing its estimation. Since wireless channels are inherently sparse, it is possible to utilize sparse representation (SR) methods to estimate the channel. In addition to sparsity feature of the channel, the...
متن کاملChannel Estimation for OFDM Systems with Multiple Transmit Antennas by Filtering in Time and Frequency
We address pilot-symbol aided channel estimation (PACE) for orthogonal frequency division multiplexing (OFDM) based systems, with multiple transmit antennas. An approach is presented which estimates and separates NT superimposed signals, corresponding to NT transmit antennas, in two dimensions. More specifically, we extend the concept of using two one dimensional (1D) estimators, instead of a t...
متن کاملAdded pilot semi-blind channel estimation scheme for OFDM in fading channels
An added pilot semi-blind (APSB) scheme used for channel identification of OFDM systems is proposed. This scheme uses pilot symbols that are added directly to the data symbols and hence does not require any additional bandwidth for its implementation. To remove the pilots, a two dimensional Wiener filter is used for the purpose of channel interpolation by using successive iterations. Although i...

This paper presents an empirical mode decomposition (EMD) based adaptive filter (AF) for channel estimation in OFDM system. In this method, length of channel impulse response (CIR) is first approximated using Akaike information criterion (AIC). Then, CIR is estimated using adaptive filter with EMD decomposed IMF of the received OFDM symbol. The correlation and kurtosis measures are used to sel...
