Carrier synchronization is a crucial part of any wireless receiver, which is required due to frequency and phase offset. In this work, we compare interpolation techniques with different FFT-based carrier synchronization methods. Applied to reference burst types specified in the DVB-RCS2 standard, trade-offs between communication performance and hardware implementation efficiency are shown. Furthermore, we present and analyze a flexible IP core implemented on FPGA.

In the paper we describe how the detection of living objects, such as people and animals, can be significantly improved. It is particularly important to detect people in dangerous environments to protect them. For such a detection task we use a radar system. Radar, because the detection also has to work at night and if it rains or snows, these are the situations when other systems, i.e. cameras, fail. Our experiments showed that many radar applications can benefit from our approach.

This paper demonstrates a squaring circuit, which is a key element in many low-power receivers, designed in a low-cost technology. For its functionality, the circuit exploits the typical characteristics of a transistor. To enhance the speed of the circuit and consequently to enable higher data rates for the receiver, a novel “boosting circuit” is implemented. An additional control circuit regulates the output and simplifies the detection of an incoming signal.

In recent years, many simulation tools emerged to model the communication of connected vehicles. Thereby, the localization accuracy due to satellite navigation systems was treated as perfect. The effect of inaccurate positioning, however, was neglected so far. This paper presents a new simulation framework that can estimate the localisation accuracy of navigation systems like GPS, GLONASS or GALILEO, based on ray optical path loss predictions (ray tracing) considering 3D building data.

In this article, we examined the emergence of the new broadcast medium Radio in Germany shortly after World War I which is called Rundfunk in this country and consider the early radio transmitter stations in Eberswalde and Königs Wusterhausen.
