SPAD-Based Optical Wireless Communication With Signal Pre-Distortion and Noise Normalization

چکیده
In recent years, there has been a growing interest in exploring the application of single-photon avalanche diode (SPAD) optical wireless communication (OWC). As photon counting detector, SPAD can provide much higher sensitivity compared to other commonly used photodetectors. However, SPAD-based receivers suffer from significant dead-time-induced non-linear distortion and signal dependent noise. this work, we propose novel OWC system which caused by dead time be successfully eliminated pre-distortion at transmitter. addition, another with joint noise normalization functionality is proposed. Thanks additional process, for transformed receiver, originally becomes independent so that conventional detection techniques designed AWGN channels employed decode signal. Our numerical results demonstrate superiority proposed systems existing terms BER performance achievable data rate.

Covert communication conceals the transmission of the message from an attentive adversary. Recent work on the limits of covert communication in additive white Gaussian noise (AWGN) channels has demonstrated that a covert transmitter (Alice) can reliably transmit a maximum of O ( √ n) bits to a covert receiver (Bob) without being detected by an adversary (Warden Willie) in n channel uses. This p...

Infrared wireless communication possesses two main attractive advantages over its radio frequency counterpart, namely the abundance of unregulated spectrum in 1.3 μm–1.55 μm region and the ease with which the infrared radiation can be confined. Integrating microwave electronics and optics, it is possible to provide wideband communication services but it is well known that the signal level in an...
