Channel Estimation Based on Trigonometric Polynomial Approximation in OFDM Systems with Transmit Diversity
Summary :
In this letter, we propose an efficient channel estimation scheme using trigonometric polynomial approximation for OFDM systems with transmit diversity. While the conventional channel estimation scheme has a high computational complexity in given channel delay profiles, the proposed scheme is efficient in the computational complexity. Especially, for channels with smaller rms delay spreads, the proposed scheme has improved BER performance and complexity reduction. In addition, we evaluate the performance of maximum delay spread estimation in unknown channel. The performance of the proposed scheme is evaluated by computer simulation in various multi-path fading environments.
