In this scheme, transmitted information is conveyed by different combinations of the positions and amplitudes of multiple optical pulses. The performance of the proposed scheme with multi\u2010pulse pulse\u2010position modulation (MPPM), G\u2010MPPM and multiple pulse amplitude and position modulation (M\u2010PAPM) schemes in terms of the number of transmitted symbols, data rate, symbol error rate (SER), bit error rate (BER), bandwidth utilization efficiency and power requirements are studied in this work. Our results reveal that, at the same frame size, the proposed scheme allows much more symbols per frame transmission, achieves higher transmission energy and further enhance the bandwidth utilization efficiency of MPPM, G\u2010MPPM and M\u2010PAPM schemes. Moreover, compared to the MPPM and G\u2010MPPM, the proposed scheme achieves lower levels of SERs but at the expense of peak power levels. Furthermore, the proposed scheme outperforms G\u2010MPPM and MPPM schemes by approximately 1 and 2 dB at a BER of 10\n                    <jats:sup>\u22126<\/jats:sup>\n                    , respectively. In addition, the analytical expressions for the BER and SER of the proposed scheme are validated using Monte Carlo (MC) simulations.\n                  <\/jats:p>","DOI":"10.1049\/cmu2.12182","type":"journal-article","created":{"date-parts":[[2021,4,5]],"date-time":"2021-04-05T02:28:54Z","timestamp":1617589734000},"page":"1700-1709","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Performance analysis of hybrid MPAPM technique for deep\u2010space optical communications"],"prefix":"10.1049","volume":"15","author":[{"given":"Sadiq","family":"Idris","sequence":"first","affiliation":[{"name":"Department of Communications Engineering University of Bremen  Otto\u2010Hahn\u2010Allee 1 Bremen 28359 Germany"}]},{"given":"Hossam","family":"Selmy","sequence":"additional","affiliation":[{"name":"National Institute of Laser Enhanced Science (NILES) Cairo University  Giza Egypt"},{"name":"Electrical Communication and Electronic Systems Engineering (ECE), Faculty of Engineering October University for Modern Science and Arts MSA  Egypt"}]},{"given":"Waslon Terllizzie A.","family":"Lopes","sequence":"additional","affiliation":[{"name":"Department of Electrical Engineering Federal University of Para\u00edba  Jo\u00e3o Pessoa, Para\u00edba Brazil"}]}],"member":"265","published-online":{"date-parts":[[2021,4,4]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"crossref","unstructured":"Edwards B.L. et\u00a0al.:An overview of NASA's latest efforts in optical communications.IEEE Int.
