In this paper, we present an analytical study of the error performance in optically
preamplified, M-ary pulse position modulation, in free-space optical communication systems …

Pulse position modulation (PPM) presents several advantages in free-space optical
systems, unrepeatered fiber transmission, and passive optical networks. In this paper, we …

M-ary pulse-position modulation (PPM) has received considerable attention for direct-

Multi-pulse pulse position modulation (MPPM) aims to improve the receiver bandwidth
efficiency with respect to M-ary PPM. It is regarded as an attractive modulation scheme that …

Monomode optical fibres currently used in optical communication systems usually have
bandwidths much greater than the information rate transmitted. This excess bandwidth can …

Multipulse pulse position modulation (MPPM) has been widely proposed to improve data
rate over the traditional pulse position modulation (PPM) in free-space optical …

A performance analysis of (XY) multiple pulse position modulation (PPM) systems, in which
X denotes the number of data slots and Y the number of pulses, operating over a plastic …

In this letter, we address two questions concerning the application of multipulse pulse-
position modulation (MPPM) for free-space optical (FSO) communications:(1) under what …

Multipulse pulse-position modulation (MPPM) is a preferred signaling scheme for free-space
optical (FSO) communications under certain constraints. In order to enable the combination …
