Talk 1: MIMO Turbo Equalization for Severe Triply-Selective Fading Channels

Severe triply-selective fading channels are found in many applications where multipath delay spread, Doppler-to-Carrier ratio, and MIMO spatial correlation are very high. Examples of such channel include digital TV broadcasting channel, shallow water acoustic channel, and amplify-and-forward relay channel. This talk will first give an overview of the technical challenges associated with such channels, then present MIMO turbo equalization techniques as a solution to enhancing performance of physical-layer receivers. An example of underwater acoustic communication is illustrated with results from several ocean experiments to compare the effectiveness of single-carrier frequency-domain Turbo linear equalization and time-domain linear or decision feedback Turbo equalization.

She is a Fellow of IEEE and a Distinguished Lecturer (DL) of IEEE Vehicular Technology Society since 2015.

Talk 2: RF CMOS Techniques for Interference and Self-Interference Handling

Interference handling, but also self-interference handling, is increasingly becoming important in radio receivers. On the one hand this is because the number of wireless devices is steadily increasing, increasing the probability that a nearby strong interferer exists. On the other hand extra interference and also self-interference occurs because multiple radios have to co-exist in one user terminal, preferably with less external components. In systems that transmit at the same time but at different frequency, duplexer filters can be used to suppress self-interference. To maximize data throughput and spectral efficiency further, it might be beneficial to not only transmit and receive at the same time but also at the same frequency. However, such full-duplex communication causes very strong self-interference, and techniques to reduce this are very much wanted. Such techniques can also relax duplex filter requirements, also creating new possibilities in half-duplex radio architectures. This workshop contribution will review some recently proposed techniques to reduce interference and self-interference.
