New Channel Estimation Scheme Exploiting Reliable Decision Feedback Symbols for OFDM Systems
نویسندگان
چکیده
The conventional pilot-aided channel estimation schemes use the fixed number of pilots to estimate the channel. In this paper, the channel estimator exploits reliable decision feedback symbols as quasi-pilots. This new channel estimation scheme is commercially attractive without additional hardware in the receiver using DSP chips for the OFDM systems.

Channel Estimation for MIMO OFDM beamforming Systems
Transmit beamforming with receive combining is a simple method for exploiting the significant diversity provided by multiple-input multiple-output (MIMO) systems, and the use of orthogonal frequency division multiplexing (OFDM) enables low complexity implementation of this scheme over frequency selective MIMO channels. A major challenge to MIMO-OFDM systems is how to obtain the channel state in...
متن کاملSubspace-based blind channel estimation for OFDM by exploiting virtual carriers
Reliable channel estimation is indispensable for orthogonal frequency-division multiplexing (OFDM) systems employing coherent detection and adaptive loading in order to achieve high data rate communications. Several options exist in practical OFDM systems—including training symbols, cyclic prefix, virtual carriers, pilot tones, and receiver diversity—to facilitate channel estimation. In this pa...
متن کاملA New Scheme of Pilot Arrangement in OFDM Systems by using a feedback Branch
Channel estimation techniques for Orthogonal Frequency Division Multiplex (OFDM) systems based on a pilot arrangement are investigated. Training based Channel estimation with a block type pilot arrangement is studied through an algorithm for determination of efficient number of pilot symbols in an OFDM symbol by adding a feedback branch. Channel estimation at pilot frequencies is based on Least...

In this paper, we propose an adaptive frequency domain channel estimation method based on a modified Kalman filtering, which requires low pilot overhead, for estimating and tracking time-varying channel in orthogonal frequency division multiplexing (OFDM) systems. The proposed frequency domain Kalman filtering channel estimation achieves the minimum pilot overhead by exploiting periodically ins...
متن کاملThe Tight Bound for the Number of Pilots in Channel Estimation for OFDM Systems
Coherent detection in OFDM systems requires accurate channel state information (CSI) at the receiver. Channel estimation based on pilot-symbol-assisted transmissions provides a reliable way to obtain CSI. Use of pilot symbols for channel estimation, introduces overhead and it is desirable to keep the number of pilot symbols as minimum as possible. This paper introduces a new tight bound for the...
