نویسندگان
چکیده
In this paper, the problem of time-varying channel estimation for ZP-OFDM wireless communication systems is considered. Based on Rayleigh Quotient Iteration method, a new adaptive blind subspace channel estimation algorithm is proposed for ZP-OFDM systems. Because SVD is not required, the new algorithm has low complexity. The performance of new method has been validated through extensive simulations.

متن کاملA subspace blind channel estimation method for OFDM systems without cyclic prefix
We propose a subspace based blind channel estimation method for OFDM systems over a time-dispersive channel. Our approach is motivated by the resemblance of the multichannel signal model resulting from oversampling (or use of multiple receive sensors) of the received OFDM signal to that in con-. ventional single carrier system 113. The proposed algorithm distinguishes itself from many previousl...

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...
