Patent ID: 8761684

Claim:
A system for testing a mobile device having a set of two or more antennas, the system comprising: a signal feed adapted to be coupled to the mobile device at a location that bypasses the set of two or more antennas; memory storing representative radiation pattern data of individual antennas in the set, and storing a propagation channel model representing amplitude and angle of arrival of one or more signal paths between a signal source and the mobile device; a channel emulator coupled to the signal feed and the memory, the channel emulator comprising one or more processors and storing instructions executable by the processors including instructions that cause the channel emulator to: align the radiation pattern data of the individual antennas in the set with the signal paths in the propagation channel model using an angular orientation parameter that relates the radiation pattern data of individual antennas in the set to the angle of arrival of the respective signal paths; apply the aligned radiation pattern data of the individual antennas in the set to the signal paths in the propagation channel model to compute a modified propagation channel model, comprising modifying at least the amplitude of the individual signal paths with the aligned radiation pattern data of the individual antennas in the set at the angle of arrival of said individual signal paths; and generate a test signal to emulate a wireless channel between the signal source and the mobile device using the modified propagation channel model, and provide the test signal to the signal feed.
