Welcome to the Institute of Digital Signal Processing!


LTE (Long Term Evolution) has been introduced as Release 8 of the 3GPP (3rd Generation Partnership Project) standard in 2008. The major advantages of LTE are high spectral efficiency, high peak data rates, low latency and frequency flexibility. Starting initially with peak data rates of up to 100 Mbps DL (downlink) / 50 Mbps UL (uplink) in 20 MHz bandwidth, enhancements towards 3 Gbps DL / 1.5 Gbps UL in aggregated carrier bandwidth of up to 100 MHz are targeted for LTE-Advanced (Release 10).

DSV’s overall expertise in this area is based on more than a decade of former industrial and academic activities of fellow employees in research, prototyping, product development, regulation, and management in telecommunications industry like software, silicon and device manufacturers and also at network operators. For instance, this includes responsibility for product verification of the LTE test mobile and LTE small cell test strategy at mimoOn GmbH in Duisburg, system architecture and technical project coordination for HSPA-Evolution and multi-carrier prototype development at ST-Ericsson in Nuremberg, UMTS FDD und TDD/TD-SCDMA standardization and terminal baseband prototype development at former Siemens Mobile Phones in Bocholt and contribution to regulation and standardization at Vodafone. Further expertise of DSV fellows cover positioning algorithms in LTE Release 9, MIMO-OFDM channel estimation and iterative receiver design, OQAM-OFDM synchronization and channel estimation.

DSV, in collaboration with industry partners and research institutes, is developing now a cognitive LTE testbed, based on commercial SDR platforms and as compliant as possible to the LTE standard. read more »
