Dataflow simulation of mixed-signal communication circuits using a local multirate, multicarrier signal representation

摘要

The explosion of the telecommunications market requires miniaturization and cost-effective realization of the front-ends of transceivers for digital telecommunications. New architectures must therefore be simulated at a high level. Current methodologies and corresponding tools suffer from common drawbacks, such as low accuracy, slow simulation speed, etc. A new methodology has been developed for efficient simulation of mixed-signal front-ends of digital telecom transceivers at the architectural level. Efficient execution is obtained using a multirate, multicarrier signal representation together with a dataflow simulation scheme that switches dynamically to the most efficient signal processing technique available. An implementation of this methodology shows both excellent runtimes and a high accuracy for realistic front-end architectures.
