  4. 3. Design of programmable multi-standard baseband processors

    Författare :Anders Nilsson; Dake Liu; Gerhard Fettweis; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DSP; baseband processor; ASIP; Computer engineering; Datorteknik;

    Sammanfattning : Efficient programmable baseband processors are important to enable true multi-standard radio platforms as convergence of mobile communication devices and systems requires multi-standard processing devices. The processors do not only need the capability to handle differences in a single standard, often there is a great need to cover several completely different modulation methods such as OFDM and CDMA with the same processing device.
