| Abstract(in English) | This paper applies a recursive eigenvalue decomposition method to the parameter update of a maximum likelihood detector with array combining for MIMO-OFDM mobile communications. This detector can suppress cochannel interference by array combining but requires a large amount of computational complexity for channel tracking owing to its conventional eigenvalue decomposition based parameter estimation. To solve this problem, the proposed method employs the recursive eigenvalue decomposition, which leads to both reducing the complexity and tracking the fading channel. Computer simulations in a fast fading channel demonstrate that the proposed scheme can maintain the BER performance while reducing the computational complexity to less than 25 percents. |
