Automotive radars play a crucial role in the reduction of traffic casualties and the realization of autonomous driving due to its robustness and adverse weather tolerance. However, as the penetration rate of automotive radars increases, concerns arise regarding the mutual interference. In contrast to the predominant Frequency-Modulated...

Automotive radar is a key element in Advanced Driver Assistance Systems (ADAS). With the growth of Automotive industry, there is a high demand for the sensors used in assisting systems. As the number of sensors increases, probability that these systems being in close proximity will also increase. This will lead to situations where in multiple...

Experimental techniques to measure rotorcraft aerodynamic performance are widely used. However, most of them are either unable to capture interference effects from bodies, or require an extremely large computational budget. The objective of the present research is to develop an XV-15 Tilt Rotor Research Aircraft rotor model for investigation of...

Boundary Layer Ingestion is an integrated propulsion concept in which a propulsor operates in boundary layer flow instead of the free streamflow with the goal to reduce the fuel flow for a given operating condition. The objective of this thesis is to obtain a better understanding of the power benefit of an installed pusher propeller at the aft...

WLAN 802.11 (WiFi) and WPAN 802.15 (Bluetooth) operate in the same 2.4GHz ISM band. OFDM WLANs are designed to provide very high data rates, resilience to multipath and extended operating range. One of the main barriers to actually achieving the high data rates is the interference from the Bluetooth systems which is one of the main sources of...

To accommodate the growing demand for wireless communications, new techniques are required to increase throughput of wireless networks. One technology aiming to increase the spectral efficiency of wireless devices is full duplex (FD) radios. These systems are capable of single carrier transmission and reception and could ideally double the...

Wireless sensor and actuator networks (WSANs) suffer from interference making them unfeasible for actuators that require reliability. This asks for an IEEE 802.15.4 behavior analysis for building automation actuators and a robust WSAN solution. This thesis uses the IEEE 802.15.4 based JenNet communication stack for experiments to define, measure...

Kalyanasundaram, P. (author)
Wireless Body Area Network (WBAN) is used for communication among sensor nodes operating on, in or around the human body in order to monitor vital body parameters and movements. A typical sensor node in WBAN should ensure accurate sensing of the signal from the body, carry out low-level processing of the sensor signal, and wirelessly transmit...

Non-coherent on-off keying (OOK) receivers are preferred in ultra low power (ULP) wireless devices as they consume less power when compared to receivers based on other modulation schemes. However, these devices are highly susceptible to co-channel interference (CCI). Therefore, interference cancellation (IC) techniques for ULP non-coherent OOK...

The demand for wireless services and the need for high data-rates are growing rapidly. Future generation networks are expected to provide high data-rates in the order of 1Gbps in local area and 100Mbps in wide area. It is a challenge for operators to meet this rising demand for high data-rates as the radio-spectrum is an expensive and scarce...

Typically, in a wireless data network, all devices use the same channel (i.e. the same frequency) so that they can easily communicate with each other. However, as node density increases, the throughput share of each device decreases due to contention of the wireless medium. It seems that the capacity problem in wireless mesh networks can be...
