In the MIMO-OFDM system channel estimation based on the superimposed pilot is one of most potential and powerful techniques for broad-band wireless communications. In most traditional algorithms, the channel parameters are estimated by calculating the first-order statistical properties of receiving information. However, there are some limitations in such methods. These methods require the first-order...
In this paper, we propose a new channel estimation algorithm for orthogonal frequency division multiplexing (OFDM) systems. For fast fading environment, we introduce a new method which is extended to the Alamouti Coded OFDM case. At the first stage of this algorithm, the channel response is estimated for pilot sub-carriers and then, the channel response for data sub-carriers are interpolated by Gaussian...
This paper proposes an iterative EQ-GM algorithm for SFBC-OFDM systems based on GM channel estimation algorithm and ZF principle. The scheme deduces a frequency domain ZF equalizer for the 2 ?? 2 SFBC-OFDM system to eliminate the channel coefficient differences of the adjacent subcarriers introduced by the frequency selective channel in order to maintain the orthogonality of the SFBC codes at the...
