A method and device for realizing smart antenna in WCDMA system are disclosed in the invention, including array antenna, radio frequency channel module, beam forming module, channel environment detection and classification module, beam-forming algorithm selection and weight value generation module. A modulated symbol sequence is segmented in a data segmentation section, and the segmented modulated symbol blocks are mapped on a plurality of carriers in a segment mapping section. The multithreading server cluster includes: at least one servlet, at least one image accessor, at least one map configuration mechanism; at least one data storage access mechanism, at least one data source manager, and at least one server-side spatial manager. , as a full transcode mode, which uses motion compensation, a requantization mode, which avoids motion compensation, or a bypass mode. A transmitter controller transmits data elements of a data element class with a highest priority first, for reaching an associated buffer fill level and then turns to data elements of successively lower priorities, until the available bandwidth is exhausted. In either case, the suspending fluid may have a density or refractive index substantially matched to that of the particles dispersed therein.
