Abstract
Next generation intelligent multimedia communications require high quality voice, graphic, video and data service over any service environment. The MIMO-OFDM systems are well known systems which are attractive for intelligent multimedia service. Among the various MIMO-OFDM systems, the SFBC-OFDM coded in space and frequency domain is a more effective system for mobile environments. In fast time-varying channels, exact channel estimation, tracking and compensation of channel distortion is essential to STBC-OFDM system The conventional channel estimation method with least-squares (LS) algorithm estimates the channel frequency response. In this paper, we propose the pilot-symbol aided channel impulse response estimator for SFBC-OFDM. Our channel estimator is effective in mobile multimedia systems.
