Simulating signal propagation effects of the mobile radio
The ability to simulate various mobile radio channel impairments, particularly, multipath fading, in the products design phase, before equalizer algorithms have been implemented as custom ASICs, is critical. This paper presents the test procedure, developed for type-approval testing of a multipath fading simulator, as well as corresponding practical measurement results in terms of spurious signals and intermodulation products, transfer functions, amplitude statistics, Doppler spectra, delay power profiles, and impulse responses, which can be used as a reference in similar situations.
