Non-Coherent UWB Communications
Non-coherent receivers have become promising candidates for low complexity and low power ultra wide band (UWB) systems.Wediscuss the performance of energy detection and differential detection in additive white Gaussian noise, Rayleigh fading, and multipath environments. It is shown that non-coherent receivers can easily collect the multipath energy by means of equal gain combing. The loss (comp...
متن کاملNon-Coherent Detection for Diffusive Molecular Communications
We study non-coherent detection schemes for molecular communication (MC) systems that do not require knowledge of the channel state information (CSI). In particular, we first derive the optimal maximum likelihood (ML) multiple-symbol (MS) detector for MC systems. As a special case of the optimal MS detector, we show that the optimal ML symbol-by-symbol (SS) detector can be equivalently written ...
متن کاملCoherent and Non-coherent Techniques for Cooperative Communications
Future wireless network may consist of a cluster of low-complexity battery-powered nodes or mobile stations (MS). Information is propagated from one location in the network to another by cooperation and relaying. Due to the channel fading or node failure, one or more relaying links could become unreliable during multiple-hop relaying. Inspired by conventional multiple-input multiple-output (MIM...
متن کاملNon-coherent Digital Modulation Classification Using Constellation Shape
This paper reports on the performance of a newly proposed modulation classification technique in a non-coherent, high noise environment. The algorithm is novel in the sense that modulation type is identified based on the shape of signal's constellation. The recovered constellation, however, is a deformed copy of the original. This deformation is modeled by a discrete non homogenous binomial ran...
متن کاملConstellation Design in an Energy-based Noncoherent Massive SIMO System
An uplink system with a single antenna transmitter and a single receiver with a large number of antennas is considered. We propose an average energy-detection-based single-shot noncoherent communication scheme which does not use the instantaneous channel state information, but uses only the knowledge of the channel distribution. The suggested system uses a transmitter that modulates information...
