A dual input-channel software defined receiver platform for GSM WCDMA and Wi-Fi

In this paper a synchronized dual input-channel multi- mode Software Defined Radio receiver platform that we built originally is presented. The receiver platform compatible with the GSM, WCDMA, and Wi-Fi standards can detect and identify the surrounding base stations and access points. It features wide frequency range, high adaptive sampling rate and especially dual phase coherent receiving channels synchronized both in frequency and time. A detailed structure of the platform and the principle of the software decoders are shown in this paper. Performance of the receiver platform for signal reception is precise and stable. Benefiting from the flexibility of the receiver function, it is not only capable of various functions, such as cognitive radio development and distributed antenna system measurement for academic research, but a dynamic platform for testing new algorithms and ideas.
