Wireless communication technology such as cellular and wireless local area network (WLAN) systems have grown rapidly and generated various competing transmission formats. In the need of seamless communication across incompatible radio standards, software defined radio (SDR) concept has received much attention among researchers working in mobile and personal wireless communications. SDR is a tec...

New wireless communications standards do not replace old ones, instead the number of standards keeps on increasing and by now an abundance of standards exists. Moreover there is no reason to assume that this trend will ever stop. Therefore, the software-radio concept is emerging as a potential pragmatic solution: a software implementation of the user terminal able to dynamically adapt to the ra...

This paper presents the architecture of a DVB-S2 receiver prototyping environment that is based on software defined radio techniques. DVB-S2 comprises the newest European standard for broadband satellite communications. The software defined radio approach enables the adaptation of the receiver to different operational modes e.g. CCM, VCM, ACM, and the support of multiple services. The prototypi...

To reduce the sampling rate in global navigation satellite system (GNSS)-radio occultation receivers, it is essential to establish a suitable estimation of Doppler frequency from the received signal in the satellite onboard receiver. This receiver is usually located on low earth orbit satellite and receives GNSS satellites signal in the occultation situation. The occurred Doppler on the signal ...

Ultra Wideband (UWB) radio system is an emerging wireless radio technology. It can transmit digital data over a wide spectrum of frequency band with very low power. This paper presents an analysis of UWB technology on direct millimeter wave six-port receiver, to be designed as an application-specific integrated receiver using Frequency Diversity Spread Spectrum (FDSS) technique. With wideband s...

Ground-breaking radio astronomy observations in the coming decade will require unprecedented levels of sensitivity while mapping large regions of space with much greater efficiency than is achieved with current telescopes. This requires new instrumentation with the greatest achievable sensitivity, dynamic range, and field of view. Receiver noise is quickly approaching fundamental limits at most...

A Software Defined Radio is a radio receiver that is reconfigurable by software. This reconfigurability leads to flexibility that can be used to offer more functionality to the user. Also, because common reconfigurable hardware can be used for very diverse radio interfaces, production and logistics can be faster and cheaper. In our Software Defined Radio project we aim at a receiver that is abl...

of software radio is the expansion of digital signal processing toward the antenna, and thus to regions where analog signal processing has been dominant so far. It is straightforward to realize that the hardware platform is a most prominent enabling component of a software radio terminal. Of special interest is the very part of the terminal where analog signal processing is replaced by digital ...

This paper identifies the issues that are important in the design of a SDR receiver. Receiver architectures are first discussed, and the conclusion drawn that the conventional superheterodyne structure is most appropriate for a SDR receiver. Issues associated with image rejection, and receiver linearity are discussed. The design of a sweepable preselect filter is discussed in detail. Design con...
