چکیده | ||
در سالهای اخیر ارسال اطلاعات مخابراتی سرعت بالا از طریق کانال انتقال قدرت (Power Line Communication) بیشتر مورد توجه محققین در عرصه مخابرات قرار گرفتهاست. در این مقاله یک الگوریتم مناسب برای تخمین کانال PLC با استفاده از مالتیپلکس تقسیم فرکانسی متعامد (Orthogonal Frequency Division Multiplexing)ارائه شدهاست. کانال PLC با ویژگیهای فیدینگ چندمسیره و فرکانسگزین تحتتأثیر نویزهای ضربهای بوده و این عوامل باعث افزایش خطا در تخمین کانال میشوند. در این مقاله، یک روش مناسب برای تخمین کانال براساس تئوری بیزین ارائه میشود. یک هسته جدید مقاوم در مقابل اثرات چندمسیره و نویزهای ضربهای با پیچیدگی محاسباتی کمتر در ماشین بردار رابط(Relevance Vector Machine)برای تخمین پاسخ ضربه کانال PLC پیشنهاد میشود. انتخاب مقادیر مناسب پارامترهای مهم این هسته جدید پیشنهادی در مدل ماشین بردار رابط، خطاهای بیتی و متوسط مجذور را بهشدت کاهش میدهد. نتایج شبیهسازی نشان میدهند که عملکرد روش پیشنهادی نسبت به روشهای ارائهشده از جمله روش Huang براساس پارامترهای مختلف ارزیابی، بهبود بیشتری یافتهاست. | ||
