Abstract
A system for emulating an over-the-air channel for communicating with a device under test is provided. The system comprises an anechoic chamber having Nprimary probes and Nsecondary probes where N>N. The system also comprises a dividing module for dividing Nprimary impulse responses {μ} into Nsubsets; and a defining module for defining Nsecondary impulse responses {v} in terms of the primary impulse responses {μ} and a set of Ncomplex sequences {λ}. In the system, either the primary probes are downlink probes, the primary impulse responses are downlink impulse responses, the secondary probes are uplink probes and the secondary impulse responses are uplink impulse responses, or the primary probes are uplink probes, the primary impulse responses are uplink impulse responses, the secondary probes are downlink probes and the secondary impulse responses are downlink impulse responses.
