This paper describes the development and proto-typing of a MIMO (Multiple-Input Multiple Output) wireless link designed to operate under the WCDMA third generation cellular standard.

The said development is performed in an integrated, system-level fashion on a DSP/FPGA development platform, the Nutaq SignalMaster. The first part of the paper will succintly describe the evolution and the main features of the WCDMA standard.

Likewise, the second part reviews the basic concepts of space-time processing and MIMO communications.

The third part details the system-level design flow and prototyping approach exploiting the strong linkage between Simulink and the SignalMaster platform.

Finally, preliminary implementation results and comparisons with other design and prototyping tools and approaches are provided.
