Abstract It is well known that the transmission of multimedia data over wireless channels poses significant constraints on the communication system bandwidth, energy, and latency. To overcome these bottlenecks to wireless multimedia communication, various adaptive compression, modulation, and channel coding schemes have been proposed. Space-time block coding (STBC) with adaptive beamforming represents an effective means of improving the performance and capacity of wireless multimedia systems utilizing OFDM. In this paper, we introduce a multimedia simulation framework employing STBC-OFDM for the investigation of system characteristics in the application of multimedia data such as, digital audio/images/video. Simulation results, based on the transmission of compressed images, showed that the performance improvement introduced by STBC-OFDM with adaptive beamforming could readily be observed even without extensive numerical analysis as traditionally expected
