Đánh giá phẩm chất mạng chuyển tiếp song công hai chiều trên cùng băng tần dưới tác động của phần cứng không lý tưởng
Abstract
Bài báo này phân tích phẩm chất mạng chuyển tiếp song công hai chiều trên cùng băng tần với phần cứng không lý tưởng, trong đó nút chuyển tiếp sử dụng giao thức khuếch đại-và-chuyển tiếp. Xác suất dừng, xác suất lỗi ký hiệu được tìm ra để đánh giá phẩm chất hệ thống. Trên cơ sở đó, để nâng cao phẩm chất hệ thống, chúng tôi tìm ra biểu thức phân bổ công suất tối ưu cho hai nút đầu cuối và nút chuyển tiếp. Kết quả phân tích đã làm rõ mức độ ảnh hưởng của lỗi phần cứng và nhiễu tự giao thoa đến phẩm chất hệ thống khi so sánh với hệ thống lý tưởng và hệ thống bán song công truyền thống. Bên cạnh đó, mô phỏng Monte Carlo được thực hiện để minh chứng cho sự đúng đắn của kết quả phân tích.References
