Efficient time-domain simulation of telecom frontends using a complex damped exponential signal model

This paper presents an efficient time-domain simulation approach for telecommunication frontends at architectural level. It is based upon the use of complex damped exponential modeling functions. These allow to construct accurate signal models for digitally modulated telecom signals, requiring only few modeling functions. Since these models are valid over a long range of time, they allow for a large timestep, which greatly speeds up time-domain simulation of the telecom frontends. Details of a simulation approach based upon this signal model are discussed. The approach is verified by experimental results
