Full duplex, low power systems, for high throughput communication and computing platforms

Enabling the 5G vision of a wirelessly interconnected ecosystem requires innovation and optimization at all levels of the hierarchy. In this talk, we first consider the system from a link enhancement perspective, where we present recent results directed at enabling Full-duplex communications. Currently systems operate in “Half duplex mode” to avoid self-saturation, where the high-powered transmitter saturates the receive path. Full-duplex transmission promises to double the spectral efficiency by allowing bidirectional communications to be carried out over the same resources. The key challenge in practical full-duplex systems is the un-cancelled self-interference power caused by a combination of hardware imperfections. We discuss recent work that identifies system limitations, performance, optimizations, and the practicality of proposed architectures.

In the second part of the talk, we consider the Achilles heel of wireless systems, namely, power consumption. Traditionally, reliability is attributed to higher power consumption. We show that this is not necessarily true. In fact, one can design systems to be both reliable (within desired specifications) and low power. We present a unique approach for power management which factors in the built-in algorithmic resilience to errors inherent in all wireless designs. This error tolerance can be utilized and co-designed with the hardware circuitry in mind to provide resilience not only to channel induced errors but also to hardware induced faults (due to low power modes), thus expanding the adaptation space to unexplored domains.
