Abstract
An access probe existing and generated within a base station to simulate a mobile terminal for the purpose of testing base station receive functionality within a communications system. The access probe data is injected at baseband rather than at RF to eliminate the need for analog/RF circuitry. The access probe performs injection at the front end of the base station receiver to exercise as much receive data path as possible. A unique ID is embedded in the access probes so that the communications system is aware which probes within a sequence were received successfully and at what power level. Within in-field applications, the unique ID allows the communications system to distinguish simulated access probes from those corresponding to real mobiles.
