This paper describes rapid prototyping in terms of a simulation prototype bridge and in terms of appropriate language design. The simulation prototype bridge combines the strengths of simulation and of prototyping allowing the designer to develop and evaluate next-generation communications systems partly in simulation on a host computer and partly as a prototype on embedded hardware. Appropriate language design allows designers to express a communications system as a block diagram in which each block represents an algorithm specified by a set of equations. Software tools developed for this paper implement both concepts and have been successfully used in the development of a next-generation code division multiple access CDMA cellular wireless communications system.

Space-time codes channel equalization and source coding are founded on complicated systems of equations and are frequently interconnected with additional signal processing algorithms. However many of these concepts prove difficult to implement in
