Because of the need for spectrally efficient systems for wireless communication, many research activities have been carried out in the area of spread-spectrum techniques. Multi-carrier spread-spectrum (MC-SS) is a new modulation technique with better spectral properties than direct-sequence spread-spectrum (DS-SS). In this paper, a new MC-SS system is(More)
Terrestrial Digital Video Broadcasting (DVB-T) is currently beeing introduced in many European countries and planned to supplement or replace current analogue broadcasting schemes in a large part of the world. It is also considered as an additional downlink medium for third generation UMTS mobile phones, where a special variant, DVB-H, is under development.(More)
Many digital signal processors (DSPs) and also microprocessors are employing the single-instruction multiple-data (SIMD) paradigm for controling their data paths. While this can provide high computational power and efficiency, not all applications can profit from this feature. One important application of DSPs are recursive filters. Due to their(More)
In order to achieve high performance and low hardware overhead over application specific integrated circuits (ASICs), application-specific DSPs (AS-DSPs) are more and more widely used. However, designing them is still a tedious, time-consuming and error-prone task since each application has to be analyzed thoroughly, which is usually done by hand. Recently,(More)
The Mobile Multimedia Modem (M3)-DSP is based on a scalable, highly parallel DSP platform concept capable of delivering the processing power to create software solutions for tasks that are currently considered ASIC-only domains, e.g. xDSL or IEEE 802.11a. The platform, consisting of the parallel signal processing engine and an Input-/ Output Processor (IOP)(More)
