Time-reversal signal processing can boost wireless comms

Space-time Blind Signal Processing for Wireless Communication Systems

In this chapter we review recent advances in space-time processing techniques for wireless communication systems. Our emphasis is on blind methods for channel identiication and signal demodulation for the receive problem. We focus mainly on the multiple user problem and provide an in-depth discussion of several approaches for exploiting signal structure in order to recover the user signals.

Low-Complexity Real-Time Signal Processing for Wireless Communications

Many signal processing algorithms in modern wireless communication systems come with a very high computational complexity. Moreover, these algorithms must be implemented in real time. Since the computational performance of digital signal processors is limited, these two requirements—dealing with arithmetic complexity and real-time constraints—are often mutually exclusive. This thesis tries to s...

Can We Investigate Direct Time Reversal Violation?

We illustrate a theoretical condition under which a two-body decay of a resonance violates time reversal invariance. Moreover, we examine some cases for which this condition looks particularly simple. As a consequence, we deduce tests of time reversal violation for weak decays involving spinning particles.
