Abstract:In free-space optical (FSO) communication, with the increase of bit resolution of M, the required bandwidth of PPM and DPIM increase sharply, and the bandwidth efficiency are extremely low. There is also a clock synchronization problem in the demodulation process of PPM and OOK. We propose a pulsed-laser pulse-number modulation (PNM) method to address the high required bandwidth and low bandwidth efficiency for high-order modulation in FSO communication with traditional modulation methods. The symbol structure… Show more
