Modern integrated circuits for wireless communication include several receive and transmit path as well as large digital blocks for signal processing. Due to the complexity of these system only event-driven simulation are fast enough for system simulation. This work describes the development of a fast and accurate event-driven frequency divider model with special focus on its transfer characteristic of harmful spurious tones. A simulation example of a receiver is given.

With the increasing amount of mobile communication, special care has to be taken to avoid collision on wireless channels. The received power in the desired band is an indicator for the utilization of this frequency range. On a receiver several ways of detecting a Received Signal Strength Indicator are available, but don't necessarily fulfill efficiency or precision requirements. Therefore, this work presents a digital implementation which is both energy efficient and precise enough.

The Internet of Things (IoT) and Industry 4.0 is evolving and has a high demand for reliable electronics. The topic is the development of a radio communication system regarding the requirements for the end user and concerning a high flexibility of the application. The result is a core board which can be combined with different sensor or actor shields to increase the flexibility and re-usability.

Power consumption in wireless networks is crucial. In most scenarios the transmission time is short compared to the idle listening time for data transmission, the most power is consumed by the receiver. In low latency systems there is a need for low power wake-up receivers (WuRx) that reduce the power consumption when the node is idle, but keep it responsive. This work presents a WuRx designed out of commercial components to investigate the needs of a WuRx when it is embedded in a WPAN.
