Automated Design of a WCDMA/WLAN Multi-standard Receiver

In this paper we show how TACT, a recently reported radio system design and optimization tool, can be used to optimize the design of a dual mode WCDMA/WLAN receiver. An overview of the underlying frequency planning and receiver budget analysis routines is discussed first. In a case study, a zero-IF WLAN/WCDMA radio receiver is then designed and optimized using the tool. TACT yields optimized design specs for each block in the chain as well as a summary of the system performance obtained. The obtained performance is shown to meet or exceed the requirements of the WCDMA/WLAN standards. As such, the case study validates the benefits of the proposed tool.
