Visible light communication (VLC) is seen as a potential access option for fifth-generation (5G) wireless communication (Wang et al., 2014) and (Ayyash et al., 2016) and beyond 5G (Strinati et al., 2019). A reliable VLC system benefits from an …
This chapter considers the estimation of amplitude, phase, frequency, and time delay in the context of the transmission of digital signals. Estimates that maximize an approximation of the proper likelihood function are derived. The performance of the …
Cooperative communication systems can effectively be used to combat fading. A cooperative protocol that can be used with half-duplex terminals is the Quantize and Forward (QF) protocol, in which the relay quantizes the information received from the …
We show that the common approach to channel and Time-of-Arrival (ToA) estimation for Impulse-Radio Ultra WideBand (IR-UWB), where the occurrence of pulse overlap is ignored, is bound to lead to considerable estimation errors in the presence of pulse …
