MmWave channels are\nsubject to Nakagami-m fading while the optical links experience the Double\nGeneralized Gamma including atmospheric turbulence, path loss and the\nmisalignment between the transmitter and the receiver aperture (also known as\nthe pointing errors). The FSO model also takes into account the receiver\ndetection technique which could be either heterodyne or intensity modulation\nand direct detection (IM/DD). Each user equipment (UE) has to be associated to\none serving base station (BS) based on the received signal strength (RSS) or\nChannel State Information (CSI). We assume partial relay selection (PRS) with\nCSI based on mmWaves channels to select the BS associated with the highest\nreceived CSI. Each serving BS decodes the received signal for denoising,\nconverts it into modulated FSO signal, and then forwards it to the data center.\nThereby, each BS can be viewed as a decode-and-forward (DF) relay. In practice,\nthe relay hardware suffers from nonlinear high power amplification (HPA)\nimpairments which, substantially degrade the system performance. In this work,\nwe will discuss the impacts of three common HPA impairments named respectively,\nsoft envelope limiter (SEL), traveling wave tube amplifier (TWTA), and solid\nstate power amplifier (SSPA). Novel closed-forms and tight upper bounds of the\noutage probability, the probability of error, and the achievable rate are\nderived. Capitalizing on these performance, we derive the high SNR asymptotes\nto get engineering insights into the system gain such as the diversity order.","url_abs":"http://arxiv.org/abs/1905.11234v1","url_pdf":"http://arxiv.org/pdf/1905.11234v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"tractable-approach-to-mmwaves-cellular","repo_url":"https://github.com/ebalti/Double-Generalized-Gamma-Distribution/blob/main/README.md","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[{"task_slug":"denoising","task_name":"Denoising"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
