چکیده
Uniform linear array (ULA)-based TDL structure offers good performance metrics when the signal sources are located at the middle angles and it shows poor performance when the signal sources are close to the array endfire. In thispaper, a new approach is proposed which offers higher performance and desired beamforming on TDL structure when the wideband uncorrelated radio sources are close to the array endfire. This new TDL structure is based on Shirvani-Akbariarray (SAA). Numerical results of this investigation show that both ULA-based and SAA-based TDL structures offer the sameperformance where the signals of interest located at middle angles. But, where the signals are close to the array endfire the SAA-based TDL structure has much higher performance. The array factor (AF) in center frequency for different angles and three well-known performance metrics, normalized meansquare error (NMSE), signal to interference plus noise ratio (SINR) and bit error rate (BER) are evaluated for both ULAbased and SAA-based TDL structuresکلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
