Slot error rate performance of DH-PIM with symbol retransmission for optical wireless links [PDF]
, 2007 In this paper we introduce the dual-header pulse interval modulation (DH-PIM) technique employing a simple retransmission coupled with a majority decision detection scheme at the receiver. We analytically investigate the slot error rate (SER) performance

A Power-Domain MST Scheme With BPPM in NLOS Ultraviolet Communications
IEEE Photonics Journal, 2023 Due to the high path loss of non-line-of-sight (NLOS) ultraviolet communications (UVC) channel, pulse modulation schemes, such as on-off keying (OOK) and M-ary pulse-position modulation (PPM), and photon-counting receivers are commonly adopted.

New Phytologist, Volume 249, Issue 4, Page 2055-2070, February 2026.Summary Plants typically host insect communities composed of multiple trophic levels that are intricately linked through interactions mediated by the shared food plant. Hyperparasitoids are top‐level carnivores in such systems, preying on parasitoid larvae developing inside herbivores. These hyperparasitoids can dramatically reduce the effectiveness of
