Reconfigurable receiver approach for future wireless terminals

Abstract

An overview on RF-front-end architectures and technologies for future reconfigurable mobile communication is given. A favourable solution for fourth mobile generation is an extension of traditional cellular parameters by OFDM-based systems like WLAN. Therefore, an approach for widely reconfigurable receivers considering a variety of different standards, with the example of combining WCDMA and WLAN front-end into one architecture, is presented in this paper. RF-front-end key components like low noise amplifiers, mixers, and frequency synthesizers, as well as baseband variable gain amplifiers and filters are treated, particularly with regard to reconfigurable systems.

BPSK receiver based on independent component analysis

“…The other type of multi-mode terminal is an economically stated reason, by integrating the old and new standards of the same family of the communication systems in the same terminals [3]. The third direction is relates to the implementation of complementary communication standards, to take advantages from the complementary communications systems [4].…”
