<p>A multi-antennae multiplexing interpolation device is used to connect a WCDMA baseband antenna interface with a RAKE receiver. It includes four functional units: a data buffer unit, an integral RAM unit, a shift integral register group and an interpolation unit. Therein, the data buffer unit is used for buffering the multi-antennae multiplexing data stream of an antennae interface, decomposing the multi-antennae multiplexing data stream into single antenna data streams and outputting them to a R interface of the shift integral register group under the control of the outside input code chip synchronizing signal and the 1/2 code chip synchronizing signal. The data stream is several sample values collected by the single antenna in one code chip period. The device adopts a real-time processing mode for the antennae sample data.</p> |
