The impact of political instability, macroeconomic and bank-specific factors on the profitability of Islamic banks: An empirical evidence

أكتوبر 10, 2017

This study investigates the impact of political instability, macroeconomic and bank-specific factors on the profitability of Islamic banks in the context of Yemen. The study used two common measures of profitability, namely, Return on Assets (ROA) and Return on Equity (ROE) as dependent variables. Seven key independent (internal and external) variables are also used. There are five fully-fledged Islamic banks (IBs) working in Yemen. The study selected only three out of five IBs due to the avail...

Comparison of RLS and LMS algorithms for interference cancelation in a fixed point to point microwave link

أكتوبر 01, 2017

/ Nazih Khaddaj Mallat / Mohammad Zia / Nada Mirza

An efficient channel estimation and interference cancelation method for a fixed point to point (p2p) microwave link is designed and investigated; it is based on Least Mean Square (LMS) and Recursive Least Square (RLS) algorithms. The LMS and RLS algorithms are compared. The objective is to minimize the computational complexity of channel estimation by using algorithms and to increase channel capacity by implementing 2×2 MIMO systems. Both the channel estimation algorithms and interference cance...
