Rotational movements such as arm, head, pitch and roll affect the received signal strength in the azimuth plane. In particular, these motions introduce changes in the antenna\u0027s location, orientation, and polarization. The degradation of the received signal caused by these motions contribute to the existing impairments that affect the quality of the communication link. Studying the signal degradation that results from random movement of the device together with other propagation conditions in the communication channel lead to a different analysis of signal impairments.\r Through computer simulations, we implemented a model for the rotational movements of the mobile device and the wireless channel. For the receiver antenna, we assume a half-wavelength dipole used in [1] while the transmitter is assumed to be non-mobile, non-rotating and uses a vertically polarized antenna. The rotational motion includes head turning during a call, body twisting or turning while holding the device, and, roll or pitch movement during interactive use. These specific movements were chosen to simplify the behaviour and scenarios. The channel model used for the non-line of sight simulation of the wireless channel is the Saleh and Valenzuela (S\u0026V) model. The S\u0026V is a two-dimensional statistical channel model representing a clustered multipath signal scenario in an indoor environment [2].\r The rotational movement of the device is integrated in the wireless communication system before summing the received signal envelopes as shown in Figure 1. These random rotational movements change the location of the receiving antenna as it spins/twists based from the angular velocity. The random rotational movements also vary the radiation pattern of the antenna projected at the azimuthal plane. The effect of the rotational movement on the wireless signal reception changes the propagation characteristic and the envelope of the received signal. These characteristics were described initially by finding the best-fit probability distribution function graphically. It was found that if the axis of rotation is away from the device (head turning or body twisting/spinning) the measured histogram of the magnitude of the received complex envelope resembles a Nakagami probability distribution curve, as shown in figure 2(a). It was also found that the magnitude of the received signals\u0027 behavior during the on-axis rotation (roll or pitch) is best fitted to the probability distribution function of Weibull, as shown in figure 2(b)."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "rotational motion"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-05-05"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "The Effect of rotational motion of a mobile receiver on the Wireless signal reception in a non-line of sight indoor environment.pdf", "filesize": [{"value": "1105 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1105000.0, "url": {"url": "https://meral.edu.mm/record/2128/files/The Effect of rotational motion of a mobile receiver on the Wireless signal reception in a non-line of sight indoor environment.pdf"}, "version_id": "7e07f494-67ac-4be8-86a0-6ccfdf23863d"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_journal_title": "8th AUN/SEED-Net Regional Conference on Electrical and Electronics Engineering"}]}, "item_1583103147082": {"attribute_name": "Conference papaers", "attribute_value_mlt": [{}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_supervisor(s)": []}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Soriano, Referendo D."}, {"subitem_authors_fullname": "Marciano, Joel Joseph S."}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Other"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Other"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2015"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "https://uyr.uy.edu.mm/handle/123456789/418"}, "item_title": "THE EFFECT OF ROTATIONAL MOTION OF A MOBILE RECEIVER ON THE WIRELESS SIGNAL RECEPTION IN A NON-LINE OF SIGHT INDOOR ENVIRONMENT", "item_type_id": "21", "owner": "1", "path": ["1582967549708"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000002128", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-03-05"}, "publish_date": "2020-03-05", "publish_status": "0", "recid": "2128", "relation": {}, "relation_version_is_last": true, "title": ["THE EFFECT OF ROTATIONAL MOTION OF A MOBILE RECEIVER ON THE WIRELESS SIGNAL RECEPTION IN A NON-LINE OF SIGHT INDOOR ENVIRONMENT"], "weko_shared_id": -1}
