<p>A base station and receiver system for use in a base station which achieves enhanced dependability by logically separating the diversity reception paths into different failure paths. In one enbodiment, the receiver system includes a first diversity reception path for receiving a first radio signal and a second diversity reception path for receiving a second radio signal. The first and second radio signals may be amplitude and phase shifted versions of the same information signal according to well known principles of diversity reception. Additionally, the first and second diversity paths are logically separated into different failure paths. Each of the paths comprises a diversity antenna and an RF front end circuit, for signal filtering and amplifying. A first and second diversity receiver, that each generates in-phase and quadrature component or IF signal samples, are coupled to the output of said first and second diversity antenna respectively. The output of each receiver is coupled to a distribution bus and afterwards to at least one demodulator for diversity combining said first and second radio signals and for demodulating said diversity combined first and second radio signals.</p> |
