End-to-end test strategy for wireless systems

Abstract

This paper proposes an end-to-end test strategy for wireless systems described by using wireless microcell as a vehicle. It presents a framework for resting digital and radio frequency (RF) boards in a wireless system and provides an integrated solution. The test strategy is based on two concepts: using boundary-scan for digital testing, and using boundary-scan to provide a gateway for DSP-based functional testing of RF circuits. The test signals are generated within the system and the test control and verification are also provided by the system leading to system self-test.
