Một đặc trưng đơn giản của hệ thống truyền thông UAV
Tóm tắt
Các phương tiện bay không người lái (UAV) có tầm quan trọng lớn trên nhiều nền tảng nhờ khả năng triển khai nhanh chóng và thuận tiện. Để có cái nhìn sâu sắc về các hệ thống truyền thông hỗ trợ UAV, cần một mô hình kênh chính xác cho các kênh UAV. Chúng tôi đề xuất một mô hình kênh tổng quát cho liên kết UAV dựa trên mô hình alpha-beta, được sử dụng rộng rãi trong tài liệu. Cụ thể, chúng tôi rút ra biểu thức chuẩn hóa của hàm mật độ xác suất (PDF), hàm phân phối tích lũy (CDF), và các số momen của mô hình đề xuất. Thành phần bóng đổ được giả định tuân theo phân phối log-normal và thành phần đa đường được đặc trưng bằng sự trợ giúp của phân phối Nakagami-m. Xác suất mất mát của một hệ thống truyền thông dựa trên UAV cũng được xác định thông qua biểu thức CDF.
