Signal constellation design is a major subtask of constructing an efficient communication system; it essentially entails trading-off error frequency against information throughput, a chief occupation of modem designers. We propose and implement an interactive tool for designing and simulating arbitrary signal constellations. To construct the user interface we have utilized Interface Builder, an interactive tool that greatly facilitates the synthesis of arbitrary user interfaces through an object-oriented paradigm. This methodology makes possible an order-of-magnitude improvement in the amount of effort required to produce a complex graphical user interface. Our secondary goal is to try to dispel some of the mystique surrounding user interface synthesis on state-of-the-art workstations.
