In one aspect, a downlink equalizer is shared between a downlink simplex port and a duplex port in a radio interface module(s) (RIM(s)) in the DAS. In another aspect, to optimize ripple reduction in the downlink equalizer, the downlink equalizer is configured to go through a plurality of downlink equalizer states that each can generate a downlink equalizer frequency response affecting downlink ripple of the RIM(s). At each of the downlink equalizer states, a test signal is provided to the downlink equalizer and a corresponding downlink ripple of the RIM(s) is recorded. When all of the downlink equalizer states are evaluated based on the test signal, the downlink equalizer is configured to function based on the downlink equalizer state associated with the smallest downlink ripple of the RIM(s)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Equalizing distributed antenna system equipped with multiple base station interface ports","description":"Optimizing ripple reductions in equalizers shared between multiple interface ports in a distributed antenna system (DAS).
