Joint source and channel coding (JSCC), multicarrier modulation (MCM) and diversity are some key techniques for multimedia transmission over wireless channels. We investigate a joint source channel matching (JSCM) scheme for progressive image transmission in the MCM system using multiple antennas. The focus of this work is on the effect of the practical channel estimation schemes on the JSCM algorithm. This is different from other research on JSCC assuming perfectly known channel information. We propose a model-based channel estimation scheme and use it.
