A novel sensitivity penalty formula is presented and verified against simulations.
WebAmplitude-shift keying (ASK) is a form of amplitude modulation that represents digital data as variations in the amplitude of a carrier wave.In an ASK system, a symbol, representing one or more bits, is sent by transmitting a fixed-amplitude carrier wave at a fixed frequency for a specific time duration.For example, if each symbol represents a single bit, then the … WebAbstract: This research evaluates the performance of On-Off Keying (OOK) Modulation on the Underwater Visible Light Communication (UVLC) system. This research analyses the performance of two types of OOK signal formats, Non-Return to Zero (OOK-NRZ) and Return to Zero (OOK-RZ).
