Noise option simplifies receiver test
Staff -- Test & Measurement World, 3/1/2004
Spirent Communications has enhanced its SR5500 wireless channel emulator with an additive white Gaussian noise (AWGN) option that eliminates the need for external noise generators in receiver tests. The option adds noise digitally to ensure test accuracy and repeatability. The SR5500 emulator mimics complex wideband radio channel characteristics such as time-varying multipath delay spread, fading, and channel loss using digital signal processing techniques.
